Literature Survey on Load Balancing Algorithm in Wireless Sensor Network

In sensor-network, enhancing network-lifetime is an essential concern due to “battery-constraints”. So maximize the duration of the network is considered as main objective while designing the algorithm. Some sensor nodes are nearer to the base-station and that nodes are burdened because they are doing a task to gather data of entire area and forward to the base-station. The tree structure is designed for collecting the data at base-station. The energy utilization of sensor-nodes depends upon various parameters like topology and resources-availability. The duration of the network increases by distributing the workload over a sensor network. This paper focuses on lifetime-maximization-problem of network using “load-balancing” method. We present an efficient-algorithm to increase the lifetime of network considering network parameter like a networkdensity using “randomized-switching-concepts”.
