Nearly Optimal Asynchronous Blind Rendezvous Algorithm for Cognitive Radio Networks
Rendezvous Time to Rendezvous Disjoint Re- laxed Difference Set Cognitive Radio Networks
2016/1/23
Rendezvous is a fundamental process in Cognitive Radio Networks, through which a user establishes a link to communicate with a neighbor on a common channel. Most previous solutions use either a centra...
An Energy-Optimal Algorithm for Neighbor Discovery in Wireless Sensor Networks
Wireless Sensor Networks Neighbor Discovery
2015/6/19
We consider sensor networks in which individual nodes with on-board sensing and low-power transmitters and receivers establish connections with neighboring nodes. The overall objective is to enable en...
A Distributed Algorithm for Maximum Lifetime Routing in Ad Hoc Wireless Networks
Wireless Networks Maximum Lifetime Routing
2015/6/19
An ad hoc sensor network of nodes with wireless transceiver capabilities is considered. We propose distributed algorithms to compute an optimal routing scheme that maximizes the time at which the firs...
An O(log n) Distributed Approximation Algorithm for Local Broadcasting in Unstructured Wireless Networks
Local Broadcasting Unstructured Wireless Networks
2012/12/4
The unstructured multi-hop radio network model, with asynchronous wake-up, no collision detection and little knowledge on the network topology, is proposed for capturing the particularly harsh charact...
The Performance of Genetic Algorithm for Synchronized Chaotic Chen System in CDMA Satellite Channel
Chaotic Chen system genetic algorithm Synchronization CDMA
2010/2/2
Synchronization is a difficult problem in CDMA
satellite communications. Due to the influence of additive noise and
fading in the mobile channel, it is not easy to keep up with the
attenuation and ...
