Performance Analysis of Communication Processor for WMSN
Main Article Content
Abstract
Wireless Multimedia Sensor Networks (WMSNs) are spread systems of wirelessly networked devices that permit retrieving video and audio streams, still images, and scalar sensor data. WMSNs will be a crucial component of mission-critical networks to protect the operation of strategic national infra-structure, provide support to counteract emergencies and threats, and enhance infrastructure for tactical military operations. To enable these applications, WMSNs require the sensor network paradigm to be re-thought in view of the need for mechanism to deliver multimedia content with a pre-defined level of Quality of Service (QoS). In this paper, an improved cross-layer communication architecture based on the multiple-input and multiple-output (MIMO) – orthogonal frequency division multiplexing (OFDM) technology is described, whose goal is to reliably and flexibly bring QoS to various applications in WMSNs and also get better life cycle parameters, by leveraging and conniving connections between different layers of the protocol stack according to application requirements. Simulations get the recital objectives of WMSNs exclusive of sacrificing on the modularity of the overall design.
