Deployment, Location Estimation and Routing in Wireless Ad hoc and Sensor Networks: Analysis & Solutions

Abstract

The use of Wireless sensor networks is an economical and efficient solution to verity of real-world problems. Sensors are low cost tiny devices with limited storage, computational capability and power. They can be deployed in large scale for performing both armed forces and civilian jobs. Deployment, location estimation and routing are the key issues through which we get the full benefits from sensors when they are used for a particular application. As sensors are energy constrained so any mechanism used for data routing must be power efficient so that it increases the sensor life time. This thesis gives the basic understanding, critical analysis and comparison of the existing techniques for node deployment, location estimation & routing in Mobile Ad-hoc Networks (MANETs) & Wireless Sensor networks (WSNs). Moreover, it introduces a novel scheme for spatial arrangement of the nodes in a circular canvas inspired by the Disk and Pizza unlike the conventional square flat-bed canvas. The circular canvas approach just perfectly synchronizes with the inherent circular range of the wireless nodes. Our research project also proposes four different schemes for node deployment, routing and location estimation in MANETs & WSNs. This project involves the evaluation of the AODV routing protocol by simulation in Network Simulator (NS) for comparison with the estimated performance of the proposed routing protocol called ‘DISK-2’.
