A Dynamic Load Balancing in Wireless CDMA Cellular Networks
نویسندگان
چکیده
With the increase of cellular users the traffic hot spots and unbalanced call distributions are common in wireless networks. The CDMA techniques enables a base tranciever station to connect microcells with optical fibers and to control the channels by sectorizing the microcells. Each sector which covers several microcells is assigned a soft channel capacity. To solve the load balancing among microcells we need to sectorize the microcells dynamically depending on the traffic required in each cell. The load balancing problem is formulated as an integer linear program which minimizes the unserved traffics and handoff calls in the network. Genetic algorithms are developed to solve the problem and computational results are discussed by comparing with other methods.

DRA: a new buffer management scheme for wireless atm networks using aggregative large deviation principle
In this paper, we present a buffer management scheme called Dynamic Resource Allocation (DRA) that provides TCP traffic control guarantees to VCs carrying multiple dynamic discard thresholds (Multiple Dynamic Thresholds—MDT) over a wireless CDMA ATM network. It is assumed that we have TCP wireless ATM networks integrating the Code Division Multiple Access (CDMA). A major task activity related t...

In 3G cellular networks, high data-rates can be achieved. However, fundamental capacity limitation still exists. Call requests are frequently blocked in hotspot areas. Load balancing among cells helps to solve this problem and to utilize the radio resources. However, existing load balancing schemes are not designed specifically for 3G networks. Some schemes are not flexible enough or even pract...
