Amassment of Data Using Energy Efficient Guide Path and Mobile Relay in Wireless Sensor Networks

There are a large number of reactive routing protocols in an Ad hoc network. The most commonly used one is Ad hoc On demand Distance Vector (AODV) routing algorithm. Establishing reliable and effective communication under the harsh environments of Industrial Wireless Sensor Networks (IWSNs) is a concerning problem that needs to be tackled efficiently. The existing system that is, Reliable Reactive Routing Enhancement (R3E) which is a modification to the existing AODV, involves a biased back-off scheme which is used during the route discovery phase to find a robust guide path. A Wireless Sensor Network may fail due to various reasons. The most concerning problem includes the node failure due to energy depletion which creates bottleneck in the network. Data gathered at the destination may not be reliable if the sensor nodes fail due to battery depletion. This project mainly deals with the concept of finding Energy Efficient Guide Path (EEGP) to provide reliable data delivery from source to destination. Failure of guide path is compensated using mobile relay which uses location based strategy to collect data from the active node and deliver it to the destination. This providesenough time for the deployment of new nodes within the network. Simulation results show that the proposed work has high packet delivery ratio and high throughput while maintaining low end-to-end delay and low packet drop.
