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.
