Abstract

Wireless Sensor Networks (WSNs) are constructed by a number of sensor nodes that are operated with restricted battery power. Sensor nodes help for sensing the data from a physical area and then send the sensed data to destination with the help of intermediate sensor nodes. One of the major problems to be addressed in WSN is improving the network coverage and lifetime. Network lifetime is affected when there is a presence of collision and interference across sensor nodes. Collision is said to be occurred in the network where two nodes try to transmit data at same time. Interference refers to the affection of data when it is transmitted from source to destination through a wireless medium. Collisions and interferences are avoided by performing load balancing among the sensor nodes in WSN. Load balancing is achieved by separating the amount of data to be transmitted in order to reduce the overload of any single sensor node.
