This paper reviews Dijkstra Algorithm implementation in finding the shortest path for route planning. The regular shortest path algorithms do not consider the timebase dynamic traffic condition of road network, i.e the hourly changing of traffic density. Timebase dynamic weight for Dijkstra Algorithm compute the most efficient time and minimum fuel(More)
This paper presents a performance evaluation of the adaptive network tree construction mechanism for ZigBee grid router network. ZigBee is a communication protocol for Wireless Personal Area Network (WPAN) which is built on the IEEE 802.15.4 standard. The low power characteristic of ZigBee is one of the main reasons in the selection of this protocol. An(More)
This paper reviews node failure detection method in ZigBee loop network. ZigBee network was popularly used for low power and low cost implementation of wireless data transmission. Node failure detection is needed in order to maintain the network reliability. Common node failure detection methods are based on ZigBee mesh networking capability. But in many(More)
In this paper, we present a new concept of ZigBee backbone by utilizing ZigBee technology for the use of low-rate wireless medium-distance link. The backbone is mainly used for connecting sensor devices around the backbone location to the gateway device. Non-beacon enabled ZigBee operation mode is considered in this backbone with ring topology enhanced by(More)
