Energy Efficiency is an important feature in poor-covered areas where not only the access to a cellular network is scarce but also energy sources are limited. In this paper, we consider a wireless mesh network to act as a local backhaul network to cover rural and remote villages. The shortage of energy in these settlements motivates to optimize the energy consumption of the wireless backhaul network...
Although the importance of Disaster Response Networks (DRNs) has been highlighted in many researches, the requirement of spectrum agility has not been well addressed. In this paper, we focus on using all-spectrum cognitive radio for DRNs to fulfill this requirement. We consider a DRN constructed by Cognitive Radio Base Stations (CRBSs), which are deployed in the disaster affected area. Each CRBS is...
Routing is an essential part of wireless sensor network and there are several methods proposed to make the scheme more energy efficient and optimal. Nowadays, many researchers are fascinated towards this topic and they have proposed typical hierarchical routing, cluster based routing, grid based routing, etc. This paper tries to make an attempt to provide a review of various hierarchical routing methodologies...
Numerous topology control algorithms for wireless sensor networks exist. Typically, these algorithms optimize general network metrics like the transmission range of sensors. Being of general nature, they suit application-specific requirements insufficiently; e.g., application-specific communication patterns may favor links that the general algorithm will remove.
Sensor networks(SN) feature low-cost sensor devices with limited wireless network capacity, transmit power and energy. This paper proposes a new routing model (Tiny Reg) based on regular-graph theory and a clustering method. By dynamically arraying cluster heads into a hierarchy transmission tree in sensor networks, our two-level approach shortens the transmission distance between cluster heads and...
A Wireless Sensor Network (WSN) is typically depicted as a distributed resource constrained platform for supporting novel pervasive applications. A possible approach is to develop applications over WSNs by resorting to mobile agent frameworks that are aimed to minimize resource costs and memory allocation. In this context, network topology is a major issue to be considered for resource optimization:...
