Optimization in a radio access network
نویسندگان
چکیده
Cellular networks are becoming increasingly complex. In coming years the introduction of third-generation networks will compound this situation. As a consequence, there is a need for simple or automated operation and maintenance (O&M), to decrease operators’ costs and to use hardware investments in the most effective way. Likewise, operators need customized functionality— a requirement that puts great demands on system flexibility. This kind of flexibility can be achieved by allowing the network to produce real-time events instead of counterbased statistics. But doing so requires an effective and well-structured network architecture. This article describes an architecture that employs event-based statistics for building effective and flexible performance monitoring and optimization applications. It also points to Ericsson system properties, activities, and experiments, showing that Ericsson is well on its way toward creating a common platform for the monitoring and optimization of second(GSM) and thirdgeneration (WCDMA) mobile systems.

متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...
