Real‐time performance evaluation of asynchronous time division traffic‐aware and delay‐tolerant scheme in ad hoc sensor networks

Abstract

SUMMARYWireless infrastructureless networks demand high resource availability with respect to the progressively decreasing energy consumption. A variety of new applications with different service requirements demand fairness to the service provision and classification, and reliability in an end-to-end manner. High-priority packets are delivered within a hard time delay bound whereas improper power management in wireless networks can substantially degrade the throughput and increase the overall energy consumed. In this work a new scheme is being proposed and evaluated in real time using a state-based layered oriented architecture for energy conservation (EC). The proposed scheme uses the node's self-tuning scheme, where each node is assigned with a dissimilar sleep and wake time, based on traffic that is destined for each node. This approach is based on stream's characteristics with respect to different caching behavioral and storagecapacity characteristics, and considers a model concerning the layered connectivity characteristics for enabling the EC mechanism. EC characteristics are modeled and through the designed tiered architecture the estimated metrics of the scheme can be bounded and tuned into certain regulated values. The real-time evaluation results were extracted by using dynamically moving and statically located sensor nodes. A performance comparison is done with respect to different data traffic priority classifications following a real-time asymmetrical transmission channel. Results have shown the scheme's efficiency in conserving energy while the topology configuration changes with time.

Efficient resource provisioning using traffic balancing in multidomain optical networks

“…Some traffic issues in the design of virtual private networks over ATM and their possible solutions have been presented comprehensively in the work of Guillemin and Hamchaoui . Traffic aware schemes for energy‐efficient routing and spectrum assignment in wireless domain have been reported extensively in the literature . Schemes that mitigate the file sharing misbehavior of vehicular peer‐to‐peer devices by using model allocation scheme for collaborating streaming in a scheduled allocation selection manner has been discussed in the work of Maromoustakis .…”

Federated broker system for pervasive context provisioning

“…there is an approximately 30% reduction in the case of the experiment iterations with no MCxB and with MCxB operating in bulk mode and using IPC communication. This conservation of energy is an important factor for the efficiency of system operation and its real world usability, keeping in consideration the ever increasing demand for high resource availability and demand for progressively decreasing energy consumption in wireless devices/infrastructures [25].…”

A Resource Intensive Traffic-Aware Scheme for Cluster-based Energy Conservation in Wireless Devices

“…Predetermined or proactive activity scheduling may decrease the network lifetime as it enables activetime uniformity, where, nodes are in active state for period of time that it is not necessary and beneficial. The activity period(s) of a node is primarily dependent on the nature and the spikes of the incoming traffic destined for this node [19]. If transmissions are performed on a periodic basis then the nodes' lifetime can be predicted/estimated.…”
