Analysis of queue load effect on channel access prioritization in Wireless Sensor Networks

Resource allocation in Wireless Sensor Networks (WSNs) is certainly a challenging issue. WSNs are characterized by special features, like energy constraints and limited computing resources. Latest trends define that sensors should be able to provide Quality of Service (QoS) demanding data transmission. A modern approach in bandwidth sharing considers both the packet queue load as well as the traffic priority. A new QoS aware channel sharing approach is introduced, analyzing the effect of queue load in WSN Medium Access Control (MAC). The analysis reveals that the queue load factor has a great impact on QoS provision in bandwidth sharing, while packet priorities are also considered.
