Abstract
WSNs with homogenous load distributions may benefit from coordinated channel access procedures. Due to the absence of DCA procedures in infrastructure-based coordinated protocols, these protocols are not as well suited for non-uniform load distributions as uncoordinated channel access protocols. Here, we introduce (DCA) a transparent dynamic allocation of channels mechanism and a co-operative load balancing (CLB) technique for cluster-based WSNs to solve this issue. These strategies were included in the protocols to enhance throughput, energy consumption, and inter-packet delay variance performance. DCA and CLB increase bandwidth efficiency under non-uniform load distributions via comprehensive simulations.
