This paper addresses the problematic of congestion control in the radio access interface when considering the allocation of voice and data services over several Radio Access Technologies (RATs). In particular, the GSMIEDGE Radio Access Network (GERAN) and the UMTS Terrestrial Radio Access Network (UTRAN) are considered for the evaluation of congestion control strategies. After a congestion situ...

A dynamic detour scheme for intelligent transportation systems (ITSs) to avoid traffic congestion is proposed in this paper. When running into traffic congestion, vehicles usually can do nothing but waiting. The proposed scheme can prevent driver suffer from traffic congestion by balancing traffic flows with nhop notices method and experience-support method. Congestive information can be receiv...

-In mobile ADHOC networks have limited bandwidth and are more prone to error than wired networks which further impose limits on the amount of data that can be sent. In order to conserve the limited resources, it is highly desirable that transmission should be as efficient as possible with minimal loss. The objective of congestion control is to limit the delay and buffer overflow caused by netwo...

The Mobile Ad hoc Network (MANET) constructs the limited range wireless communications model in which nodes construct a temporary network and communicate with each other. It's communication completely depends on the intermediate nodes and the bandwidth they can provide. As the resources, routes, and bandwidth are limited MANET finds difficulties for communication when high traffic occurs and ca...

In this paper, we discuss a cross layer congestion control technique of TCP Reno-2 in wireless networks. In this both TCP layer and PHY layer jointly control congestion. The PHY layer changes transmission power as per the channel condition, interference received and congestion in the network, whereas the TCP layer controls congestion using Reno-2 window based flow control. Our simulations show ...

Widespread use of computer networks and the use of varied technology for the interconnection of computers has made congestion a signi cant problem. In this report, we summarize our research on congestion avoidance. We compare the concept of congestion avoidance with that of congestion control. Brie y, congestion control is a recovery mechanism, while congestion avoidance is a prevention mechani...

Congestion on the roads is a key problem to deal with, which wastes valuable time.. Due to high mobility rate and relative speed link failure occur very often. VANET is used to tackle the problem of congestion, and make decisions well in advance to avoid traffic congestion. In this paper we proposed a solution to detect and control the traffic congestion by using of both (V2V) and (V2I), as a r...
