Guaranteed Time Slot

In this work, energy-efficient adaptive duty cycle guaranteed time slot algorithm is proposed for beacon-enabled standard medium access control protocol to efficiently handle low, medium and high data traffic loads. The proposed protocol can efficiently handle high traffic load by effective utilization of slots. The protocol can dynamically update the number of slots for contention access period and contention free period in each beacon interval. Therefore, it can capably handle high network load condition. The protocol continuously monitors the utilization capacity of each of the sensor node and allots the contention free period slots to the needy nodes based on their utilization capacity. Simulation analysis is done for three different scenarios. The performance of the proposed protocol is compared with the other existing protocols. Simulation results show the overall superiority of our proposed algorithm in terms of packet delivery and energy consumption.

Hydrological Monitoring

In order to cope with the existing shortcomings lie in hydrological monitoring areas, a novel hydrological monitoring system based on beacon-enabled ZigBee network is proposed in this paper. The designed monitoring system is made up of three parts: field collecting portion, field monitoring portion and remote service portion. The proposed data collecting station utilizes ZigBee for delivering field sensors' data to monitoring center, which is designed to collect, store, process and analyze the data and provide higher services to the hydrological department. The main idea about constructing a simple and effective beacon-enabled ZigBee network is presented. The improvement on Guaranteed Time Slot (GTS) assignment mechanism and low power consideration are also be involved. The practical results indicate the system is effective and reliable.
