Improving ZigBee Networks Robustness with Multi-channel Capability

Based on IEEE 802.15.4, ZigBee is developed for low-power and low-data-rate wireless communication and it is building up remarkable position for wireless sensor network (WSN). As ZigBee is using the 2.4GHz Industrial, Scientific, and Medical (ISM) unlicensed frequency band, coexistence issues arise as there are also other wireless technologies...

A Framework For Coping With Intra-Node Adjacent Channel Interference In Multi- Channel Multi-Radio Mesh Networks

Typically, in a wireless data network, all devices use the same channel (i.e. the same frequency) so that they can easily communicate with each other. However, as node density increases, the throughput share of each device decreases due to contention of the wireless medium. It seems that the capacity problem in wireless mesh networks can be...

Multi-channel services for click and mortars: Development of a design method

The rise of Internet commerce led to multiple predictions of disintermediation and the decline of physical shopping. However, a "click and mortar" approach, which combines online, offline and telephone contact, has added value for customers and for supplier profitability, as recent research confirms. Our research objective was to help...
