An energy balanced mobile agents based data dissemination protocol for wireless sensor networks

Due to multi-hop routing and many-to-one data traffic pattern of wireless sensor networks (WSNs), the sensor nodes near to the sink have heavier relay traffic that makes them to deplete their energy much faster than sensor nodes in other parts of the monitored space. This uneven energy consumption can cause energy hole around the sink. During this case, the sensed data cannot be successfully routed to the sink. To deal with this problem, we propose an energy balanced mobile agents based data dissemination (EBMADD) protocol that employ multiple mobile agents for data aggregation and collection task. We performed simulation experiments to evaluate the performance of the EBMADD protocol and the results show that our proposed protocol will balance the energy consumption among all the sensor nodes and prolong the lifetime of network.
