Sharing information among nodes is a key function in Wireless sensor networks (WSNs) applications. Gossip protocols can be employed to facilitate data exchange and ensure data delivery to a sink node. In this paper, we propose two protocols to enhance the traditional gossip protocol by providing lightweight distance-based methods for selecting the next optimal node to retransmit a message. The first proposed protocol, NNGossip, uses the nearest neighbor distance measure, while the second, CBGossip, uses the city block distance measures. The major advantage of using these two techniques is that the computation is simple and fast and hence preserves the energy. We evaluated the performance of the proposed protocols against the traditional gossip protocol, Gossiping, and the Fair Efficient Location-based Gossiping protocol, FELGossiping. The experimental results show that using the proposed protocols maximize the network lifetime and insures efficient bandwidth while maintaining the delay at a low level.
