Abstract
The energy consumption of nodes is strictly limited in wireless sensor networks. The traditional direct delivery routing protocol is employed in the paging network of high-rise building construction elevators, which results in the high energy consumption and low successful delivery rate. A load-balancing equal opportunity routing protocol for wireless paging network is proposed in this work. The load-balancing equal opportunity routing protocol is a data transfer technique which maintains the network survivability by selecting the optimal path with both the lower energy consumption and the balanced network load. A load-balancing scheme gives equal opportunities for package transmission. A pager node delivers the packages by selecting a neighbor node with higher energy. The neighbor nodes in the coverage of the source node have an equal opportunity for routing. The sink node in the paging network broadcasts routing messages when moving along the track during the path selecting. The proposed load-balancing equal opportunity routing protocol is implemented and evaluated in a high-rise building construction elevator. The experimental results show that the average energy consumption of nodes is lowered with a balanced network load. It is estimated that successful delivery rate is increased by 55% but with a higher latency, and the network lifetime is prolonged.
Highlights
A wireless sensor network (WSN)[1,2,3] is a self-organized wireless network consisting of a large number of spatially distributed sensors or nodes to monitor physical or environmental conditions
A large number of broadcast packages are produced in the paging process because the packages that are transmitted with direct delivery (DD) algorithm result in low successful delivery rate (SDR) of data, and increase time delay and energy consumption
According to the construction hoist’s working environment, a load-balancing equal opportunity (LBEO) routing algorithm is presented in this article to reduce the power consumption and ensure the fair and balanced energy consumption among nodes
Summary
A wireless sensor network (WSN)[1,2,3] is a self-organized wireless network consisting of a large number of spatially distributed sensors or nodes to monitor physical or environmental conditions. As in a WSN, the nodes in WPN contain several technical challenging issues These may include the radio, battery, microcontroller, analog circuit and the lifetime constraints imposed by the limited energy power of the nodes in the network. The direct delivery (DD) algorithm is in practice an available solution to reduce the package collision rate in the WPN It shows some limitations in terms of QoS. A large number of broadcast packages are produced in the paging process because the packages that are transmitted with DD algorithm result in low successful delivery rate (SDR) of data, and increase time delay and energy consumption. According to the construction hoist’s working environment, a load-balancing equal opportunity (LBEO) routing algorithm is presented in this article to reduce the power consumption and ensure the fair and balanced energy consumption among nodes. The SDR is increased and the average energy consumption of the node is lowered but with higher packet latency
