Evaluation of wireless Ad Hoc Protocols using random motion

Abstract

The evolution of wireless communication and circuit technology has enabled the development of an infrastructure which consists of sensing, computation and communication units that makes administrator capable to observe and react to a phenomenon in a particular environment. The building block of such an infrastructure is comprised of hundreds or thousands of small, low cost, multifunctional devices which have the ability to sense compute and communicate using short range transceivers known as sensor nodes. The interconnection of these nodes forming a network called wireless sensor network.

Ad hoc networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology. Thus the need is there for a tough dynamic routing protocol that can accommodate such an environment. The report consists of elaborate description of three different Ad Hoc routing protocols– DSDV, DSR and AODV.

As there are numerous studies that have already taken place for basic routing protocols we focused on basing our study for random motion. This allows us to obtain a more realistic data as not all nodes stays stationary. A prototype was used to run simulation based on different scenarios under random functions that obtained significant results in order to highlight the strength and weakness of the protocols through analyzing performance indicators, namely throughput and goodput.
