Improvement of AODV routing protocol in extensive non-stationary ZigBee networks

ZigBee is a standard of IEEE802.15.4 protocol and generally classified as a low-power and low-cost Wireless Personal Area Network (WPAN). Energy consuming and delay time are the the most challenging issues in ZigBee network and there are different methods for reducing power usage and latency in networks but every method needs a cost function to be defined and determining effective parameters for cost function is the main subject in different methods. Some algorithms offer to reduce energy consumption of battery but in most cases this vantage leads to increasing delay time in routing process and this phenomenon in large mobile networks is very harmful because reliability and stability of these systems are very important for developers. Such networks need low-power and low latancy factors concurrently. In this paper a customized Ad hoc On-Demand Distance Vector (AODV) routing method has been proposed for decreasing delay time of network without any influences in power usage. In this method data is forwarded through an energy efficient and modified path.
