Controlled Multi-Path Routing in Sensor Networks Using Bezier Curves
Source: Oxford University Press
The authors address the problem of extending the lifetime of wireless sensor networks using multi-path routing based on a family of flexible routes with soft quality of service guarantees in terms of the packets' delivery latency. They introduce a methodology based on Bezier curves as guiding trajectories in the routing process and they address the balancing of the workload among neighboring nodes. An added benefit, due to the flexibility of the Bezier curves, is that the shapes of the (alternate) routes can be constructed in a manner that prolongs the lifetime of the nodes in the vicinity of a given source/sink.
