Abstract

In wireless sensor networks, some areas often become unavailable due to the exhaustion of nodes' energy, congestion, or disaster. In this paper, we propose a new micro sensor multi-path routing protocol (MSMRP) to avoid the unavailable areas when constructing the routes. A neighbor node table exchanging mechanism in MSMRP is used to avoid the multiple paths intersect and to build a new route around the unavailable areas. We have implemented the proposed protocol in a network with real sensor nodes and conducted experiments to demonstrate the operation and the capability of the MSMRP. Furthermore, we illustrate the performance of MSMRP comparing to ad hoc on demand multi-path distance vector (AOMDV) routing protocol with NS-2 simulations.
