Performance analysis and impact of different mobility model on specific configured network with IEEE 802.15.4for WSNs

Abstract

Wireless Sensor Network is the set of homogeneous or heterogeneous sensor nodes; those can sense the data from different sensing areas of the network. There are different routing protocols exist for find the efficient route to transmits the data from source to destination. The performance of the routing protocols depends of the various factors in the network like packets size, types of signals, movement of nodes (mobility model), data transmission rate, power consuming rate and types of topologies or network architecture. The consuming of battery power is the serious issue for the performance of routing protocols in the network, in term of lifetime of the network and packets delivery ratio as well. Initially, that is considered different routing protocols with different topologies and also considered mobility model like Random way point mobility and group based mobility for the analysis then evaluate the performance. Mobility model highly impact on the performance of routing protocols and lifetime of the network because movement of the nodes consumed more energy than stationary nodes. That routing protocol namely as AODV routing protocol performed without relay point architecture. In this paper, evaluate the performance of AODV protocol with star topology using different mobility models. Performance analysis and evaluation has been done on the different metrics like jitter, throughput, packets dropped, End to End delay, energy consumption in different processing modes and percentage of time consumed in different processing modes. Simulation has been done on the QualNET 5.0; the analysis shows variation in the performance on different metrics.
