An energy-efficient architecture of wireless home network based on MAC broadcast and transmission power control

To construct an energy-efficient wireless home network based on IEEE 802.15.4, a novel architecture is proposed. In this architecture, all nodes are classified into stationary nodes and mobile nodes according to the functionality of each node. Mobile nodes are usually battery-powered, and therefore...

Description
Summary:To construct an energy-efficient wireless home network based on IEEE 802.15.4, a novel architecture is proposed. In this architecture, all nodes are classified into stationary nodes and mobile nodes according to the functionality of each node. Mobile nodes are usually battery-powered, and therefore need low-power operation. In order to improve power consumption of mobile nodes, effective handover sequence based on MAC broadcast and transmission power control based on LQ (link quality) are employed. Experimental results demonstrate that by using the proposed architecture, communication time and power consumption of mobile nodes can be reduced by 1.2 seconds and 42.8%, respectively.
