A Novel MAC Protocol with Different QoS for WMSNs Materials
The adoption of wireless multimedia sensor networks (WMSNs) by applications that require complex operations, ranging from health care to industrial monitoring, has brought forward a new challenge of fulfilling the quality of service (QoS) requirements of these applications. Since the requirements depend on the applications, it would be difficult to design a single MAC that satisfies the wide range of applications. This calls for a suitable MAC protocol capable of achieving application-specific QoS. In this paper, we have proposed a novel MAC protocol with different QoS for WMSNs, which not only adapts to application oriented QoS, but also attempts to conserve energy without violating QoS-constraints. Simulation results demonstrate that the proposed protocol is capable of providing a bound latency including real-time and better throughput, at the cost of reasonable energy consumption, in comparison to other existing MAC protocols.
