A Fuzzy Logic-Based and Distributed Gateway Selection for Wireless Sensor Networks
"... Wireless sensor networks are resource-constrained because of the difficulty of recharging the devices. In order to prolong the network lifetime, the nodes relaying packets should carefully be selected. In a scenario where multiple sinks (gateways) are available, this selection is extended to decide ..."

A Combined Relay-Selection and Routing Protocol for Cooperative Wireless Sensor Networks
, 2013
"... Abstract—In wireless sensor networks several constraints decrease communications performances. In fact, channel randomness and energy restrictions make classical routing protocols inefficient. Therefore, the design of new routing protocols that cope with these constraints become mandatory. The main ..."

Constructing Minimum Relay Connected Sensor Cover in Heterogeneous Wireless Sensor Networks
"... Abstract. Energy efficiency is an important problem in wireless sensor net-works. In this paper, we consider the energy efficiency problem in a hetero-geneous wireless sensor network which consists of energy-constrained sensor nodes and resource-rich relay nodes. We firstly formulate the minimum rel ..."

Relay Selection for Geographical Forwarding in Sleep-Wake Cycling Wireless Sensor Networks
"... Abstract-Our work is motivated by geographical forwarding of sporadic alarm packets to a base station in a wireless sensor network (WSN), where the nodes are sleep-wake cycling periodically and asynchronously. We seek to develop local forwarding algorithms that can be tuned so as to tradeoff the en ..."

Energy Efficient Data Transmission through Relay Nodes in Wireless Sensor Networks
, 2012
"... Abstract—In a Wireless Sensor Network (WSN) having a single sink, information is given to the distant nodes from beacons by overhearing. Since it is out of the communication range, information is not sent directly to the static sink (SS). If a distant node is not able to communicate directly, then i ..."

, then it should send its own packet to another node which is closer to the Base Station (BS) so that the received packets are relayed to the BS by this node. In this paper, we propose a relay node selection algorithm to reduce contention and improve energy efficiency. In this algorithm, each data packet of direct
