Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
