Multiple Mobile Sink Weighted Rendezvous Planning and Interference- Aware Path Selection in Wireless Sensor Networks

Wireless sensor networks consist of many sensor nodes installed in an area. One of the major problems in WSN is energy efficiency. Many studies have revealed that Mobile sink can be used to reduce the energy consumption in nodes and to prevent the formation of energy holes in Wireless Sensor Networks. The existing uses a hybrid moving pattern where the mobile sink visits only the rendezvous points (RP). In order to choose a optimal route to visit the RPs Weighted Rendezvous Planning is used where a weight is calculated and assigned to every node based on the hop distance from tour and the amount of data packets that gets transmitted to the closest RP. In the proposed method, an innovative technique is introduced which is called Multiple Mobile Sink Weighted Rendezvous Planning and Interference-Aware Path Selection (MMSWRP-IPS) for placing multiple mobile sinks and reducing interference. In this technique the network is divided into smaller regions and for each region a mobile sing will be assigned.
