Adaptive Channel Reservation Scheme
نویسندگان
چکیده
Due to the high mobility of low earth orbit (LEO) satellites, there is a significant number of handover attempts in a LEO satellite mobile communication system, causing a high handover failure rate. This paper proposes an Adaptive Channel Reservation Scheme (ACRS) which gives an overall optimal success rate for both handover and new call initialisation. ACRS is able to adapt to the local traffic condition and makes the best decision on the timing of sending out a channel reservation request. A simulation model has been built and tested on uneven traffic density condition. Promising results have been obtained and they agree with theoretical expectation. Key-Words: Satellite mobile communications, Handover, Channel reservation

Adaptive channel reservation scheme for soft handoff in DS-CDMA cellular systems
Soft handoff techniques in direct-sequence code-division multiple-access (DS-CDMA) systems provide mobile calls with seamless connections between adjacent cells. Channel reservation schemes are used to give high priority to more important soft handoff attempts over new call attempts. However, since the number of soft handoff attempts varies according to environmental conditions, fixed reservati...
متن کاملAdaptive Admission Control for next Generation Networks
This paper investigates the adaptive local resource reservation call admission control protocols. The algorithms are built upon the concept of guard channel and we use an adaptive algorithm to track the optimal number of guard channel resources to reserve at a base station. We compare the following adaptive algorithms, one based on the Wiener prediction theory and the other based on the arrival...
متن کاملPredictive channel reservation for handoff prioritization in wireless cellular networks
In wireless cellular networks, a roaming mobile station (MS) is expected to move from one cell to another. In order to ensure that ongoing calls are not dropped while the owner mobile stations roam among cells, handoff calls may be admitted with a higher priority than newly generated calls. Predictive channel reservation (or pre-reservation) schemes allow the reservation of a channel for an ong...
متن کاملAdaptive Trunk Reservation Policies in Multiservice Mobile Wireless Networks
We propose a novel adaptive reservation scheme designed to operate in association with the well-known Multiple Guard Channel (MGC) admission control policy. The scheme adjusts the MGC configuration parameters by continuously tracking the Quality of Service (QoS) perceived by users, adapting to any mix of aggregated traffic and enforcing a differentiated treatment among services during underload...
متن کاملDesign and performance analysis on adaptive reservation-assisted collision resolution protocol for WLANs
In conventional IEEE 802.11 medium access control protocol, the distributed coordination function is designed for the wireless stations (WSs) to perform channel contention within the wireless local area networks (WLANs). Packet collision is considered one of the major issues within this type of contention-based scheme, which can severely degrade network performance for the WLANs. Research work ...
