Multiple Traffics Support in Wireless Body Area Network over Cognitive Cooperative Communication

摘要

the main difference between traditional wireless sensor networks (WSN) and wireless body area network (WBAN) is the traffic nature. Where, in the WBAN the traffic can be classified into two types, normal and critical traffics, critical traffic should be deliver to destination efficiently. In this paper, we designed a cognitive cooperative communication with two master nodes, namely as critical data transmission over cognitive master nodes (CDT-CMN). We provide mathematical model of the link, outage probability of the proposed protocol. The results demonstrate that the CDT-CMN is achieve better performance with respect to direct transmission mode (DTM).
