In this paper, we investigate the impact of antenna orientation on the performance of
wireless sensor networks. In the experiments conducted using Crossbow MicaZ motes we …

In this paper, the values of received signal strength indicator (RSSI) are studied for various
deployment environments in wireless sensor networks. The accurate RSSI estimation can …

Energy-efficient node placement is one of the main design issues for linear structure
wireless sensor networks. Two types of node placement schemes studied in the paper are to …

Due to the power limitation in wireless sensor nodes, special attention is required in
optimizing the power consumption of the necessary electronics on a node. This can be done …

The hop distance strategy in wireless sensor networks (WSNs) has a major impact on
energy consumption of each sensor mote. Long-hop routing minimizes reception cost …

The energy of the power supply units for wireless sensor network node is finite and the node
is uneasy to replace, so the energy consumption is a key problem in wireless sensor …

We investigate the problem of converting sets of sensors into strongly connected networks of
sensors using multiple directional antennae. Consider a set S of n points in the plane …

We propose a power efficient system architecture that exploits the characteristics of sensor
networks in order to decrease the power consumption in the network. The primary …

A mobile wireless sensor network owes its name to the presence of mobile sink or sensor
nodes within the network. The advantages of mobile WSN over static WSN are better energy …

In the sensor network the nodes which are nearer to the base station (BS) have additional
communication loads of forwarding data generated by distant nodes. Thus they lose their …
