Energy limitation is the main concern of any wireless sensor network application. The
communication between nodes is the greedy factor for the energy consumption. One …

Multi-channel based routing approach may utilize more than one channel for communication
and has the ability to provide high performance by more rigorously countering interference …

We investigate the following fundamental question—how fast can information be collected
from a wireless sensor network organized as tree? To address this, we explore and evaluate …

In traditional wireless sensor network (WSN) applications, energy efficiency may be
considered to be the most important concern whereas utilizing bandwidth and maximizing …

The ability of newer generations of commercially available radios used on the sensor nodes
to tune their operating frequency over different channels provides an opportunity to alleviate …

Wireless sensor networks (WSNs) have captivated substantial attention from both industrial
and academic research since last few years. The major factor behind the research efforts in …

In this paper, we formulate multi-channel assignment in Wireless Sensor Networks (WSNs)
as an optimization problem and show it is NP-hard. We then propose a distributed Game …

Unlike the scalar data (such as temperature, pressure and humidity), the vector data (such
as image, audio and video) necessitates more stringent Quality of Service (QoS) …

In this paper, multi-channel allocation in wireless sensor and actuator networks is formulated
as an optimization problem which is NP-hard. In order to efficiently solve this problem, a …

This article considers the data aggregation scheduling problem, where a collision-free
schedule is determined in a distributed way to route the aggregated data from all the sensor …
