TelG Mote: A Green Wireless Sensor Node Platform for Smart Home and Ambient Assisted Living

The wireless sensor network(WSN) consists of sensor nodes that interact with each other to collectively monitor environmental or physical conditions at different locations for the intended users. One of its potential deployments is in the form of smart home and ambient assisted living(SHAAL) to measure patients or elderly physiological signals, control home appliances, and monitor home. This paper focuses on the development of a wireless sensor node platform for SHAAL application over WSN which complies with the IEEE 802.15.4 standard and operates in 2.4 GHz ISM(industrial, scientific, and medical) band. The initial stage of SHAAL application development is the design of the wireless sensor node named Tel G mote. The main features of Tel G mote contributing to the green communications include low power consumption, wearable, flexible, user-friendly, and small sizes. It is then embedded with a self-built operating system named Wise OS to support customized operation. The node can achieve a packet reception rate(PRR) above 80% for a distance of up to 8 m. The designed Tel G mote is also comparable with the existing wireless sensor nodes available in the market.

Joint Routing and Admission Control in Wireless Mesh Network

Wireless Mesh Network is a promising technology with many challenges yet to be addressed. Novel and efficient algorithms need to be developed for routing and admission control with the objective to increase the acceptance ratio of new calls without affecting the Quality of Service (QoS) of the existing calls and to maintain the QoS level provided for the mobile calls. In this paper, a novel Markov Decision-based Admission Control and Routing (MDACR) algorithm is proposed. The MDACR algorithm finds a near optimal solution using the value iteration method. To increase the admission rate for both types of calls, a multi-homing admission and routing algorithm for handoff and new calls is proposed. This algorithm associates the user with two different access points which is beneficial in a highly congested network and proposes a new routing metric to assure seamless handoff in the network. Our proposed algorithm outperforms other algorithms in the literature in terms of handoff delay, blocking probability, and number of hard handoff.

Zigbee-based new approach to smart home

Smart home is a promising solution to improving the quality of people's life.Much work has been done in the field,but most of these solutions are just based on home gateway,leaving much to be improved.One of its defects is the relatively high energy consuming and its radiation,and the other is that it is not available to the old home appliances which fail to access the internet.Full use of the low energy consuming characteristic of the Zigbee wireless sensor network,a completely new smart home solution is put forward in this paper.Without need of a home gateway and any modification for the currently used family appliances,the method uses the Zigbee coordinator as the central controller and the controllers of appliances as the end devices of Zigbee.It can realize a comfortable and smart home.Experiments show that the scheme proposed is feasible and it will be no doubt to be able to improve the quality of people's daily life.
