Multiple Access System Designs via Genetic Algorithm in Wireless Sensor Networks

چکیده
Recently, a distributed estimation, a type of parameter estimation problem, has been widely studied from the viewpoint of wireless sensor network (WSN) applications (1) (2). In particular, distributed estimation has been well-studied for certain WSN applications, such as environmental monitoring and precision agriculture (3)-(8). In such applications, measurements are acquired by the combination of a large number of deployed sensors which are equipped with a radio communication transceiver and a fusion center (FC), which collects measurement information from sensors to obtain a final estimate. Such measurement systems require some multiple access systems such as time division multiple access (TDMA), frequency division multiple access (FDMA) (9), frequency and time division multiple access (FTDMA) (10). However, most of related works ignore the effect of multiple access techniques on distributed estimation in WSNs.

A 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...
