Efficient set routing for continuous patient monitoring wireless sensor network with mobile sensor nodes

Abstract

Static sensor nodes are effectively and efficiently replaced by mobile sensor nodes in WSN applications like tracking, periodic weather monitoring, etc. In this paper, challenges in WSN routing are focused with mobile nodes. A new routing protocol called as set routing is proposed for wireless sensor networks with mobile nodes. In set routing, the sets of nodes are constructed after deployment. Routing overhead is fully given to static sink node or base station. Direction based linear mobility pattern is chosen for its greater coverage area with low energy spent and is used in set routing. Set routing is simulated using Omnet++ and Matlab and the performance is studied. The results are compared with cluster based routing and mobile leach protocols and found that delivery ratio is higher in our set routing.
