Existing works on data aggregation in wireless sensor networks (WSNs) usually use a single channel which results in a long latency due to high interference, esp
To improve spectrum efficiency (SE), the adaptive modulation and coding (AMC) and automatic repeat request (ARQ) scheme have been combined for MIMO systems. In
Fourth generation wireless communication systems feel the necessity of transparent and seamless user roaming with end-to-end connectivity. These systems also de
With the development of mobile technology, especially the development of 3G and mobile IP, the computational capacity of handsets is becoming more and more powe
