Extensive research is being done on Wireless sensor Networks (WSNs) in present decade. WSNs consist of large number of sensor nodes which perform sensing of certain phenomena and send the sensed data to the sinks. This operation consumes energy of sensor nodes which effects the lifetime of a network. To prolong the lifetime of WSNs various strategies and routing algorithms have been proposed. Use...
Wireless sensor network includes base station (sink) and battery operated sensor nodes. A sensor's energy is consumed to transmit data to the sink. Thus, a sensor's energy depletes with time. Energy consumption can be reduced by using the mobile sink which communicates between end user and sensor nodes. Mobile sink usage requires efficient reconstruction of routes from a sensor to the mobile sink...
Wireless sensor network is a distributed system for sensing and monitoring the incorporated environment. Generally congestion in WSN network occurs due to transmission of packet in the inappropriate path from source to destination. Congestion in network creates additional load to the network.

Energy problem is an important consideration in wireless sensor network. It is because sensor nodes in network use limited battery source which leads to limited lifetime. Also, sensor nodes in WSNs use multi-hop communication, so nodes near sink node transmit more data compared with farther nodes. These phenomenon results in energy hole problem which is critical to prolong lifetime of sensor network...
