Wireless sensors nodes are broadly used in the area of remote monitoring such as habitat tracking, wild life monitoring, weather and tsunami alert. These nodes require less administration since they are placed in remote locations, and battery power is needed for them to sustain their lifetime. Since the nodes are placed in remote location, powering up the nodes is often impossible. Autonomic computing is needed in these situations so that sensor nodes can supervise themselves without being monitored by human. Hence a mobile agent assisted self-healing sensor network is proposed in our work. Simulation results are presented to validate our protocol in terms of energy efficiency and self-healing. The idea then further expanded into in a real world prototype specifically into intrusion detection system within buildings. Preliminary results of the prototype exhibit that the system is feasible to be deployed in a real world scenario with the energy efficient routing protocol. This gives innovation into energy efficient routing protocol in wireless sensor areas. Copyright © 2013 ACM.
