Abstract There are different protocols for realising WPAN. ZigBee protocol supports high node density, long range and robust communication and hence chosen for experimenting in WPAN. ZigBee protocol may not be adequate to bring all the consumer electronic devices under WPAN and control them as the devices may use different protocols. ZigBee stack is taken as base, it is modified to incorporate the features of common communication protocol so as to enable the consumer electronics share resources and communicate among themselves leading to a virtual control network. As the internet is most commonly used communication network in the user community, the protocols of internet are studied to find the suitability in channel access and routing strategies in order to implement in the modified ZigBee stack. After a thorough research ZigBee stack is modified with appropriate protocols at respective layers with the addition of new layer between network and application layers. This work presents the mathematical modelling of the modified ZigBee stack, christened ZI stack. Four different metrics viz., throughput, delay, transmit energy and receive energy are modelled and the results of experimentation are also presented. The ZI and ZigBee stack are compared w.r.t. various metrics. The theoretical and practical values of performance metrics are tabulated in this paper.Keywords: LWIP, TCP/IP, ZI, RIP, CSMA and WSNCite this Article A. Narmada, P. Sudhakara Rao.
