Resource reservation mechanisms for distributed multi-path quality of service routing
نویسندگان
چکیده
This paper studies resource reservation mechanisms that can be incorporated into distributed multi–path Quality– of–Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Simulations are carried out to compare the performance of the protocols and to study the impact of system parameters on the performance of the protocols. Our results show that, in most of the cases, backward reservation protocols are more efficient than their forward reservation and hybrid reservation counterparts.

Impact of Resource Reservation on the Distributed Multi–path Quality of Service Routing Scheme
This paper studies the impact of resource reservation on the multi–path Quality–of–Service (QoS) routing schemes that use global network state to make routing decisions. Incorporating resource reservation into multi–path QoS routing algorithms greatly changes the communication characteristics in a network system and affects the performance of the routing algorithms. In this paper, we develop a ...

متن کاملAgent based Bandwidth Reservation Routing Technique in Mobile Ad Hoc Networks
In mobile ad hoc networks (MANETs), inefficient resource allocation causes heavy losses to the service providers and results in inadequate user proficiency. For improving and automating the quality of service of MANETs, efficient resource allocation techniques are required. In this paper, we propose an agent based bandwidth reservation technique for MANET. The mobile agent from the source start...
متن کاملAdaptive Routing In Dynamic Ad-Hoc Network
The dynamics of an ad hoc network are a challenge to protocol design because mobility of nodes leads to unstable routing, and consequently flows encounter fluctuations in resource availability on various paths during the lifetime of a session. This has become serious, especially for those protocols based on single-path reservation, as frequent reservation and restoration of reservation-based fl...
