Efficient and deadlock-free routing is critical to the performance of networks-on-chip. In this paper we present ail approach that can be coupled to an), adaptive routing algorithm to improve the performance with a minimal overhead on area and energy consumption. The proposed approach introduces the concept of Neighbors-on-Path to exploit the situations of indecision occurring when the routing Junction returns several admissible output channels. A selection strategy is developed with the aim to choose the channel that will allow the packet to be routed to its destination along a path that is as free as possible of congested nodes. Performance evaluation is carried out by using a flit-accurate simulator on traffic scenarios generated by both synthetic and real applications. Results obtained show how the proposed selection policy applied to the Odd-Even routingalgorithm outperforms other deterministic and adaptive routing algorithms both in average delay and energy consumption.

The use of the wireless sensor networks (WSNs) should be increasing in different fields. However, the sensor's size is an important limitation in term of energetic autonomy, and thus of lifetime because battery must be very small. This is the reason why, today, research mainly carries on the energy management in the WSNs, taking into account communications, essentially. In this context, we compare different clustering methods used in the WSNs, particularly EECS, with an adaptive routing algorithm that we named LEAM This algorithm is based on topological self-organizing maps. We obtain important gains in term of energy and thus of network lifetime.
