Given the increasing demand from wireless applications, designing energy-efficient group communication protocols is of great importance to multihop wireless networks. A group communication session involves a set of member nodes, where each of them needs to send a certain number of data packets to all other members. In this paper, we consider the problem of building a shared multicast tree spanning...
Wireless sensor network (WSN) has been considered to be the next generation paradigm of structural health monitoring (SHM) systems due to its low cost, high scalability and flexibility. However, some inherent limitations of WSN such as low-bandwidth wireless communication, limited resources on wireless sensor nodes, must be addressed to meet the generally high requirements of SHM. Distributed in-network...
Efficient implementation of FIR (finite-impulse-response) equalizers for wireless channels has attracted much attention these days as equalizations can improve the link performance in hostile mobile radio environment by compensating for inter-symbol interference created by multipath within time dispersive channels. Meanwhile, the MIMO (multiple-input-multiple-output) technique becomes a trend in wireless...
