A Taxonomy of Space-time Processing for Wireless Networks
نویسندگان
چکیده
A taxonomy of space-time signal processing is addressed in terms of architectural and algorithmic classiication, and the innuence of the propagation channel on the space-time processing. The architecture is classiied according to link structure, channel reuse and multiple access scheme. Algorithms are classiied into channel estimation methods, TDMA and CDMA receive algorithms and space-time transmit algorithms. Finally, the eeects of Doppler spread, delay spread and angle spread on space-time processing is adressed.

A Novel Comprehensive Taxonomy of Intelligent-Based Routing Protocols in Wireless Sensor Networks
Routing in ad-hoc networks, specifically intelligent-based ones, is a highly interested research topic in recent years. Most of them are simulation-based study. Large percentages have not even mentioned some of the fundamental parameters. This strictly reduces their validity and reliability. On the other hand, there is not a comprehensive framework to classify routing algorithms in wireless sen...
متن کاملA Deterministic Multiple Key Space Scheme for Wireless Sensor Networks via Combinatorial Designs
The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...
