In this paper we introduce a new routing algorithm

for wireless sensor networks. The aim of this algorithm is to

provide on-demand multiple disjoint paths between a data source

and a destination.

Our Multipath On-Demand Routing Algorithm (MDR) improves

the reliability of data routing in a wireless mobile network

while maintaining the amount of overhead traffic at a low value.

An important feature of MDR is that it is very robust against

the average speed of the nodes in the network. Even for very

high values of the mobility, the algorithm succeeds in delivering

the data to the destination.
