Abstract
Gossip-Based Sleep Protocol (GSP) is a routing protocol in the flooding family with overhead

generated by duplicate packets. GSP does not have other sources of overhead or additional

information requirements common in routing protocols, such as routing packets, geographical

information, addressing or explicit route computation. Because of its simple functionality, GSP is a candidate routing protocol for Wireless Sensor Networks. However, previous research

showed that GSP uses the majority of energy in the network by keeping the nodes with their

radios on ready to receive, even when there are no transmissions, situation known as Idle

Listening. Complementing GSP implies creating additional protocols that make use of GSP

particular characteristics in order to improve performance without additional overhead. The

research analyzes the performance of GSP with different topologies, number of hops from source

to destination and node densities, and presents one alternative protocol to complement GSP

decreasing idle listening, number of duplicate packets in the network and overall energy

consumption. The study compared the results of this alternative protocol, MACGSP6, to a

protocol stack proposed for Wireless Sensor Networks: Sensor MAC (S-MAC) with Dynamic

Source Routing (DSR), showing the advantages and disadvantages of the different approaches.
