Geometrical Shape Based Multipath Routing in WSNs

ABSTRACT Wireless Sensor Networks (WSNs), multipath routing facilitates energy efficient routes and reliable for critical information delivery to the sink node from an event occurrence node. In this paper employ a set of static and mobile agents for developing Geometrical Shape Based Multipath Routing in WSNs (GSBMR). Each sensor node is assumed to know the location information of the sink node and event node. In the proposed work Event node computes arbitrary distance, Straight Route Special Intermediate Nodes (SRSINs), Special Top and Bottom nodes (STN and SBN) and shortest distance between event node and sink node by using location information. In GSBMR mobile agent migrate from one node to another along the straight above the reference axis and below reference axis. During the traversal each mobile agent gathers the node information (node id, location information, residual energy, available bandwidth, neighbors’ connectivity the partial topology information) and delivers it to the sink node. Using the partial topology information, Sink node compute node disjoint multiple routes and route weight factor by using energy ratio, link efficiency and hop distance for all route discovered by the mobile agent. Depending on the criticalness of event the sink node selects a single route for emergent data delivery or multiple routes for reliable data delivery. To validate the proposed scheme, we have simulated the scheme for various performance parameters.
