Wireless Sensor Network (WSN) is comprised of small and low-cost sensors deployed in a particular region in order to monitor a phenomena. In this paper, we have addressed some problems, which have significant effects on the performance of WSNs while computing the path from source to the base station. Although in the literature, many MAC protocols for WSNs have been proposed based on QoS to save the...
Wireless Sensor Networks (WSNs) comprise of groups of tiny sensor nodes that are deployed for collaborative missions such as environmental monitoring, target tracking and surveillance. Due to the miniature size of the nodes, they are typically deployed in large numbers and communicate via multiple hops through a wireless shared communication channel. The successful implementation of such networks...
The following topics were dealt with: electromagnetic compatibility; mobile wireless networks; QoS; ad hoc networks; RFID; protocols; multimedia system; virtual reality; signal processing; coding; telecommunications services; network operations and management; information infrastructure and security; communication theory; communication software.
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
