An Intelligent Cross-Layer QoS-Aware Protocol with Traffic-Differentiation-Based for Energy Efficient Communication in WSNs

Abstract

Despite an increase in energy efficiency of WSNs research in couple of last years, still the key challenge in the design of WSNs remains to maximize the quality of service (QoS) and energy efficiency of network system. The layered strength and functionality collaboration is commonly considered as one of the most promising techniques for dealing with the given challenge to increase the duration between recharging battery and improve energy efficiency in order to prolong the sensor nodes and network lifetime. This paper presents a novel Intelligent Cross Layer QoS-aware Protocol (I-XLP) with traffic differentiation for WSNs for monitoring applications which has been done by addressing cross layered, cluster-less and application specific design. The target application is building monitoring. The novel concept behind this paper is that, by leveraging classical layered approach and blending different layer functions our proposed protocol I-XLP achieves a solution for energy efficiency and latency for the case of building monitoring applications of WSNs. This is done by combining the strong functionalities of Medium Access control (MAC), Routing and Congestion control. The proposed protocol is energy efficient and the protocol ensures lower latency for the prioritized traffic. Our proposed I-XLP is simulated by using the network simulator (ns-2). The simulation results corroborate the theoretical idea, and verify that the proposed I-XLP transmits more data with less delay and its energy consumption compared with existing protocol achieves optimum energy efficiency.

Design of Joint Cooperative Routing, MAC and Physical Layer with QoS-aware Traffic-based Scheduling for Wireless Sensor Networks

“…In literature we found that several protocols have been considered the energy efficiency parameter as a main attribute design of a protocol [1], [2], [4], [7], [16]. For example, we focus on the protocol presented in [1], [7] and [16] by authors, as we used to target in our work.…”

“…4. According to [3][4], synchronization of frame is maintained by virtual clustering. During virtual clustering, sensor nodes can handle different schedule from its neighbour hop and each node is given a unique identification number (ID).…”

“…The results are shown both for the prioritized traffic and non-prioritized traffic. The parameters of our experiments are defined in Table 2, which are consistent with those from [4].…”

“…Since the prime issue of WSNs which is considered to design a communication protocol is energy efficiency. most promising and potential field of application of WSN includes industrial, medical facilities, home appliance and buildings monitoring and control networks [1] [2] [4]. In most of the cases the applications developed by the WSNs is consist of a large number of wireless sensor nodes in a random manner.…”

“…Meanwhile, the cross-layer protocol for WSN which is one of desirable approach to achieve and upgrade the performance parameter metrics of protocol design is still under work for its state maturity life cycle. Nevertheless, a number of researcher concentrate on designing cross-layer protocol in the literature [1], [2], [4], [7], [16], which are discussed in section 2 of this paper. In this work, we propose a cross layer protocol together with joint routing, MAC, and Physical (J-RMP) layer for energy efficient wireless sensor network.…”
