While a lot of existing research attempts to extend the lifetime of a wireless sensor network
(WSN) by designing energy efficient networking protocols, the impact of random device …

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 a wireless sensor network, a sensor measures environmental data. It also relays data for
other sensors. While sensing workload is the same among sensors, relaying workload …

Placement of relay nodes is a critical issue in provisioning large-scale wireless sensor
networks. Lifetime and connectivity are the two most important factors that need to be …

In this paper, the problem of relay node placement in heterogeneous wireless sensor
networks (WSNs) is addressed. As all nodes are energy limited, placement strategies aimed …

Scalability and extended lifetime are two critical design goals of any large scale wireless
sensor network. A two-tiered network model has been proposed recently for this purpose …

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 …

A two-tiered network model has been proposed for prolonging lifetime and improving
scalability in wireless sensor networks (Gupta, G. and Younis, M., Proc. IEEE WCNC'03, p …

Device deployment plays a key role in the performance of any large-scale wireless sensor
network (WSN) application. WSN device deployment (ie the numbers and positions of the …
