Abstract

In an ad-hoc wireless sensor network systems, the life time of sensor nodes is a crucial issue to ensure sustained functionality of the network. For a multi hop wireless sensor network the routing protocol used plays an important role in prolong the life time of the nodes. In this work, a routing technique based Ant Colony Optimization technique has been used and performance evaluation of different network topology is studied such as flat and clustered network. The system has been tested using six Telosb sensor nodes programmed with nesC language based Tinyos 2.1.2 under Linux operating system. Also a python program has been used to monitor the performance of the network and collect the required data. The obtained results shows a good performance in power consumption when using clustering technique rather than other network topologies.
