Unattended deployment and energy constrained nature of sensor nodes motivates the need of designing reliable, energy efficient Wireless Sensor Networks (WSN). Events generate data, which is relayed to the BS though multiple-hops. Although data transfer over multiple-hops minimizes total transmission power, energy of sensors on routing path from event to BS depletes quickly compared to other nodes. Sensor nodes near the Base Station (BS) get heavily loaded with data from the network, leading to dead sensors and connectivity holes in the network. This thesis, proposes a scheme of enhancing network lifetime by employing multiple dynamically mobile BSs in an event driven WSN. Employing dynamically mobile multiple BSs can balance the energy consumption throughout the network. Large-scale networks can benefit by dividing the network in smaller sub-regions and assigning a mobile BS to each sub-region. The BSs move in a controlled manner towards events, thereby reducing the distance traveled by data packets and hence conserving network energy. The BSs also consider various parameters like event area, priority and distance while making relocation decisions. Simulation results show that dynamic mobility of multiple BSs towards events increases the network lifetime significantly, decreasing overall energy consumption of network. Higher energy savings are achieved in networks with more number of BSs as compared to networks with less number of BSs.
