TBF-based multipath tolerant routing for sensor networks

In sensor networks, the bad working conditions make nodes have high failure probabilities, so the routing algorithms must be able to recover from failure of nodes. And multipath is a method to resolve it. In this paper, we propose a new algorithm to construct multipath based on TBF (Trajectory-Based Forwarding) which was proposed as a middle-ground between source-based routing and greedy forwarding techniques. And it is very easy to construct disjoint or braided multipath. And we also evaluate the performance in isolated or patterned failure mode.
