Multi-hop wireless sensor networks with a single Sink are attractive from a cost point of view.
When battery-driven, these networks suffer from the energy hole problem, where the nodes …

In this paper, we discuss how cooperative transmission (CT) can provide better services
and/or lower the initial cost compared to non-CT in wireless sensor networks. To see the …

In this paper, we study the impact of cooperative routing for maximizing the network lifetime
in sensor network applications. We assume nodes in the network are equipped with a single …

Theoretically optimal performance and behavior of a routing protocol are very important
because they can be used to guide the design of practical protocols. Motivated by the …

Employing cooperative communication in multihop wireless sensor networks provides the
network with significant energy efficiency. However, the lifetime of such a network is directly …

Although current research focused on sensor deployment to balance the energy
consumption among the sensor nodes for prolonging the lifetime of wireless sensor …

In this paper, we study the impact of cooperative routing for maximizing the network lifetime
in sensor network applications. We assume nodes in the network are able to perform …

Energy hole is an inherent problem in wireless sensor networks, which results from heavier
traffic loads of nodes nearer to the sink, and leads to significant network lifetime reduction …

The energy balancing capability of cooperative communication is utilized to solve the energy
hole problem in wireless sensor networks. We first propose a cooperative transmission …

Due to the limited transmission range, data sensed by each sensor has to be forwarded in a
multi-hop fashion before being delivered to the sink. The sensors closer to the sink have to …
