ZigBee is a current wireless standard based on IEEE 802.15.4 used in Wireless Sensor Networks (WSNs) stimulates many interests. In a built WSN, the information about some part of interest may need further research such that more traffic will be generated. Earlier work presented adoptive-parent-based framework for a ZigBee cluster-tree network which provided more flexible routing and increase bandwidth utilization without violating operating principles of ZigBee cluster-tree protocol. However, sensed data collectors may vampire the optimality and convergence rate of bandwidth utilization demands. In this paper presents an Enhanced Distributed Adoptive Parent (EDAP) framework for ZigBee cluster tree topology which handles varying traffic load communication in any given instant for WSN communication. In EDAP framework, traffic load conditions are tested at real time mode i.e., bursty ones. Divergent traffic load minimizer technique is employed to evaluate the actual required bandwidth on traffic load instances of ZigBee cluster tree communication. Sensed data collectors are appropriated to traffic load demand for efficient WSN communication. Simulations are carried out to evaluate the efficacy of EDAP framework for WSN communication in cluster tree topology in terms of Traffic Load, Frequency of Load variance, Bandwidth rate, Communication overhead and Load-Bandwidth Divergent Rate.
