Analysis and Assessment of Power Consumption for Routing Protocols in MANET

Abstract

Recently, the lack of independent wireless networks deployment was the main reason not only loosing victims but also diminution of the performance of security forces and first aids services during natural disasters and wars. Mobile Ad Hoc Networks (MANET) is the technology of choice used in such critical situations where the infrastructure of wireless networks fails to work. MANET relies on its nodes to forward and route packets that gives it a characteristic of an independent network. The independence here means that the network relies on its battery power to achieve its routing. In this research work, we study two types of MANET protocols belonging to different kinds of routing protocol categories: namely reactive protocol and proactive protocol in terms of power consumption. More specifically, we are interested on the Destination-Sequenced Distance-Vector (DSDV), Optimized Link State Routing (OLSR), Ad Hoc On-Demand Distance-Vector (AODV) and Dynamic Source Routing (DSR) protocols to investigate how much power they consume at different layers, operation modes, routing overhead and MAC load. In order to achieve the goal of performance study, we choose some scenarios that can be adapted to different MANET contexts: such scenarios carried out when network area size, network density, pause time and mobile node speed are changing. Extensive simulations and results for these scenarios obtained by NS2 simulation software.
