Realizing machine-to-machine (M2M) communications requires to construct and to manage scrupulous connections (logically and physically) from devices controllers to an enormous number of devices. By leveraging existing cellular infrastructures providing higher layers connections, the most challenging task is to efficiently manage massive accesses on the air interface. Consequently, in this letter,...
This paper discusses load balancing architecture among heterogeneous wireless networks (HWNs). Load balancing is an important issue for efficient use of radio resources not only in a single network but among different radio access technologies (RATs) in HWNs. Cooperative management of radio resources among heterogeneous RATs is considered to reduce imbalance of utilization of radio resources and enhance...
In third generation (3G) wireless systems we have a number of resources being used exclusively and simultaneously to satisfy the requirements of an arriving multimedia call. This would require the occupation and release of these resources to be in a manageable fashion. In this paper, we discuss a multi-component teleservice model for multimedia applications. Subsequently, based on this teleservice...
In next generation heterogeneous networks, mobiles users want to benefit from all the advantages of the integrated access networks by switching between them dynamically. In this paper, we propose a novel scheme for reducing handoff delay using the received signal strength (RSS) and the mobile station speed to reserve available resources for a user from its adjacent cells according to its current position...
The operator of an UMTS radio access network has to define timeout thresholds for the radio resource control protocol. These timeouts have a strong influence on the quality of service of the user traffic. In general long timeouts favour the call setup time over the outage probability. For short timeouts it is the other way around. Furthermore the reached quality of service level depends on the load...
