An Energy-Efficient Clique-Based Geocast Algorithm for Dense Sensor Networks

Abstract: This paper proposes an energy-efficient geocast algorithm for wireless sensor networks with guaranteed delivery of packets from the sink to all nodes located in several geocast regions. Our approach is different from those existing in the literature. We first propose a hybrid clustering scheme: in the first phase we partition the network in cliques using an existing energy-efficient clustering protocol. Next the set of clusterheads of cliques are in their turn partitioned using an energy-efficient hierarchical… Show more

“…Survey on typical geocast approaches [20] reveals that most of them cannot guarantee delivery to all nodes inside a region. This is usually caused by either the partitioning of network inside the region [21], [22] or routing failure [23]. GeographicForwarding-Geocast (GFG) and Geographic-ForwardingPerimeter-Geocast (GFPG) [24] guarantee reachability by flooding queries to a specific region.…”

“…In the literature, several energy aware algorithms [16][17][18][19] have been proposed for WSN. There are also several routing algorithms proposed for WSN which focus on reliable data delivery [20][21][22][23][24][25][26][27].…”

“…For multiple geocast regions there are few works including [14], [15], [16], [17]. The work in [15] relies on flooding to discover routes to the geocast regions using "route discovery" and "route reply" messages.…”

“…This approach clearly does not scale with network node density and quantity. Also relying on flooding but with a hierarchical approach, [16] groups nodes into clique-clusters. A super cluster head is elected among these cluster heads.…”
