In this paper we propose a novel data dissemination protocol for multisink wireless sensor networks based on a geographic random forwarding routing approach. The proposed protocol exploits the intrinsic broadcast nature of the wireless channel in order to allow a reliable and efficient data delivery to a set of data sink in networks with an aggressive power-off strategy. We focus our analysis on the multihop performances in term of the average amount of hops to reach all the destinations. The proposed scheme performance is evaluated by means of both simulation and analytical techniques that lead us to give some discussion about parameter tuning related to sensor density.

Abstract
In this paper we propose a novel data dissemination protocol for multisink wireless sensor networks based on a geographic random forwarding routing approach. The proposed protocol exploits the intrinsic broadcast nature of the wireless channel in order to allow a reliable and efficient data delivery to a set of data sink in networks with an aggressive power-off strategy. We focus our analysis on the multihop performances in term of the average amount of hops to reach all the destinations. The proposed scheme performance is evaluated by means of both simulation and analytical techniques that lead us to give some discussion about parameter tuning related to sensor density.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
