Abstract

A wireless mobile sensor network is a group of independent wireless mobile sensor nodes which forms a temporary network without the use of any centralized management or fixed infrastructure. Communication protocols are responsible for maintaining the routes in the network and guarantee reliable communication. On the other hand, appropriately adjusting the sensors transmission power is crucial for reducing network energy consumption. This paper proposes a comparison of routing strategies and the impact of variable transmission power for each mobile sensor node on the performance of these communication techniques for mobile wireless sensor networks with the aim of outlining design considerations of protocols for mobile environments. We analyze the performance of both reactive routing protocols Ad hoc On Demand Distance Vector protocol (AODV), Dynamic Source Routing (DSR) protocol and proactive protocol Destination-Sequenced Distance Vector routing protocol (DSDV) in different scenarios. The selected protocols are compared on the basis of various parameters, which include packet delivery ratio, total packet loss, network lifetime, and control overhead using variable number of nodes and speeds.
