In wireless sensor networks nodes forward the data they acquire from the environment
towards the base station by relaying through multiple intermediate sensor nodes used as …

The authors propose three variants of distributed and stateless forwarding strategies for
wireless sensor networks, namely greedy minimum energy consumption forwarding protocol …

In hostile environments where explosives and natural calamities probably occur, wireless
sensor networks (WSNs) are susceptible to multiple collocated failures and could be …

We investigate the benefits of a heterogeneous architecture for wireless sensor networks
(WSNs) composed of a few resource rich mobile relay nodes and a large number of simple …

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 consider neighbor sensor networks which are defined as multiple wireless
sensor networks under the administration of different authorities but located physically on …

In a heterogeneous wireless sensor network (WSN), relay nodes (RNs) are adopted to relay
data packets from sensor nodes (SNs) to the base station (BS). The deployment of the RNs …

In this paper, cooperative sensor protocol and relay deployment in wireless sensor networks
(WSNs) is proposed to improve the network lifetime. First, cooperative transmission is …

Sensors are used to monitor and control the physical environment. In mobile sensor
networks, nodes can self-propel via springs, wheels, or they can be attached to transporters …

An important issue in the design of a wireless sensor network (WSN) is to devise techniques
to make efficient use of its energy, and thus, extend its lifetime. When two WSNs are …
