Book Description

Overview and Goals Wireless communication technologies are undergoing rapid advancements. The past few years have experienced a steep growth in research in the area of wireless ad hoc networks. The attractiveness of ad hoc networks, in general, is attributed to their characteristics/features such as ability for infrastructure-less setup, minimal or no reliance on network planning and the ability of the nodes to self-organize and self-configure without the involvement of a centralized n- work manager, router, access point or a switch. These features help to set up a network fast in situations where there is no existing network setup or in times when setting up a fixed infrastructure network is considered infeasible, for example, in times of emergency or during relief operations. Even though ad hoc networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to scalability, quality-of-service, energy efficiency and security.

Book Description

Master's Thesis from the year 2013 in the subject Computer Science - Miscellaneous, grade: -, , course: Master of Technology, language: English, abstract: Wireless Sensor Networks (WSNs) are highly integrated technologies applying sensors, microcontrollers and wireless networks technologies. Wireless sensor networks (WSNs) is a promising technology that has a large spectrum of applications such as, battlefield reconnaissance, border protection and security surveillance, preparing forecasts, severe environment detection, volcano monitoring, disaster management. WSNs operate unattended in harsh environments with limited energy supplies that can’t be practically changed or recharged. Thus energy efficiency is a critical design issue which must be addressed. Clustering plays an effective role in judicious use of dwindling energy resources of the deployed sensor nodes. Nodes are grouped into clusters and a specific designated node, called the cluster head is responsible for collecting data from the nodes in its cluster, aggregating them and sending to the BS, where data can be retrieved later. Besides energy efficiency, clustering has many other advantages like reduced routing overhead, conservation of communication bandwidth, stabilized network topology, network stability etc In this research, we study the energy efficiency of two clustering algorithms, S-Web and LEACH and compare them for network lifetime. Simulation results show that the S-Web clustering mechanism achieves a noticeable improvement in the network lifetime.

Book Description

The emergence of powerful hand held devices like cell phones, personal digital assistants (PDA), pagers coupled with the advancement of wireless communication system have paved the way for a variety of mobile computing and wireless networking technology recently. The history of wireless networking goes to early days Defense Advanced Research Projects Agency packet radio network. The advantage of wireless networking is its ability to support user mobility and has created a new breadth to problem solving in this domain, resulting in unpredictable resource requirement and uncertainty in network connectivity. Solutions to these problems have boosted the market for wireless services. Wireless ad hoc network is a collection of mobile devices forming a network without any supporting infrastructure or prior organization. Nodes in the network should be able to sense and discover with nearby nodes. Due to the limited transmission range of wireless network, multiple network “hops” may be needed for one node to another (source to destination or intermediate node) across the network. There are number of characteristics in wireless ad hoc networks, such as the dynamic network topology, limited bandwidth and energy constraint in the network. Mobile ad hoc network plays an important role in different applications such as military operations to provide communication between squads, in emergency cases in out-of-the-way places, in medical control etc. Routing protocols play a significant role in the implementation of mobile ad hoc networks (MANET). Due to the characteristics of mobility of ad hoc networks it is crucial to find a path or route from the source to the destination node and perform the communication between nodes for a long period of time. In MANET, a number of routing protocols using a variety of routing algorithms has been proposed – for example Dynamic Source Routing (DSR), Ad hoc On demand Distance Vector Routing (AODV), Temporally Ordered Routing Algorithm (TORA), Location Aided Routing (LAR) and periodic (proactive) protocols such as Destination Sequence Distance Vector (DSDV), Distributed Bellman Ford, where member nodes exchange routing information and know a current route to each destination periodically. Also, several protocols uses both reactive and proactive mechanisms, such as Zone Resolution Protocol (ZRP) Cluster Based Routing Protocol (CBRP) etc.

Book Description

Wireless networking covers a variety of topics involving many challenges. The main concern of clustering approaches for mobile wireless sensor networks (WSNs) is to prolong the battery life of the individual sensors and the network lifetime. For a successful clustering approach, the need of a powerful mechanism to safely elect a cluster head remains a challenging task in many research works that take into account the mobility of the network. In Mobile, Wireless and Sensor Networks: A Clustering Algorithm for Energy Efficiency and Safety, the authors use an approach based on computing of the weight of each node in the network as the proposed technique to deal with this problem. They present a virtual laboratory platform (VLP) of baptized mercury, allowing students and researchers to make practical work (PW) on different aspects of mobile wireless sensor networks. The authors’ choice of WSNs is motivated mainly by the use of real experiments needed in most college courses on WSNs. These usual experiments, however, require an expensive investment and many nodes in the classroom. The platform presented here aims at showing the feasibility, the flexibility, and the reduced cost using the authors’ approach. The authors demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs. The book will be a valuable resource for students in networking studies as well as for faculty and researchers in this area.
