A Review of ZigBee-UMTS Hybrid Networks
A ZigBee network is a low-cost and low-power wireless network based on the IEEE 802.15.4 standard, which allows wireless connectivity with limited power and relaxed throughput requirements. On the other hand, the Universal Mobile Telecommunications System (UMTS) is a third-generation cellular network that provides high-speed wireless traffic transfer to the internet. This paper presents the design and implementation of a novel integrated ZigBee and UMTS hybrid network in the Network Simulator (NS-2). In this hybrid network, the authors design a new mobile gateway to interconnect these two different sub-networks.
