Load Balancing On Gateway Nodes Using Bootstrapping Approach In Wireless Sensor Network

摘要

Sensor nodes sense the actions in the particular region and corresponds data back to the Base Station (BS) with higher region of interest. Base station is capable of delivering the packets in the higher speed but do not offer the longer communication over the dynamic sensor network environments. The longer communication network structure plans to minimize the end-to-end delays among the packet transmission but the instantaneous queue size attains the higher computational complexity. To offer the longer communication network structure with lesser computational complexity, Bootstrapping path based Load Balancing (BLB) Approach is proposed in this paper. BLB Approach enables the network scalability to huge number of sensors for the effective network communication. BLB Approach set up the network with two steps. Initial step is the bootstrapping path, where gateways are discovered within the sensor network range. BLB broadcast the packet to the longer dynamic path in the sensor network. Second step is the grouping in BLB approach, where the packets are grouped at the particular instance of time. The grouping of packets on the base station avoids the collisions. After the grouping step in BLB, all the sensors in wireless network are informed about the identity of the group they belong. The sharing of common information in sensor network balances the load effectively by reducing the computational complexity. BLB approach performs the longer communication over the dynamic sensor network environments and measures the computational complexity. Experiment is conducted on the factors such as packet delay rate over longer path communication, computational complexity and reordering time taken on receiver side.
