“…The search was done very carefully, because we discovered that the optimum average packet delay is extremely sensitive even to small changes in the value of the and that it does not seem to exist a unique pattern exhibited by the optimal d values. Finally, it is interesting to nd how far the average packet delay can be from its optimum value, when using d =1 in (2) for all values. The above packet retransmission policy does not optimize the average packet delay with respect to the parameter d, however, it is simpler to implement.…”

We consider the random multiple access of a slotted broadcast communication channel. Packet arrivals for such channels are often modeled as Poisson processes because the latter have attractive theoretical properties and are well understood, even though a number of tra c studies have shown that packet interarrival times are not always exponentially distributed. For example, recent studies argue convincingly that tra c from a variety of working packet networks (e.g., LANs, WANs, e.t.c), is much better modeled using statistically self similar processes to characterize the packet interarrival times of the aggregate tra c, which have much di erent properties than Poisson processes. Because of the great in uence the multiple access algorithms (used in the channel access subsystem) will have on the performance of third generation digital wireless mobile communication systems, we study in this paper the problem of random multiple access under a packet tra c generated by interactive data applications (e.g., reading/composing short email messages, responding to paging type messages, transferring les between the mobile and a xed computer, and querying of a database). We examine and demonstrate the performance robustness of the above RAAs when they are driven by a strongly bursty packet arrival process, commonly found in interactive data applications.

“…For example, Mahdavi et al [7] suggests a voice-data mixed service traffic model nomenclature of 'Delay of Voice End-User' (DOVE) using one dimensional Markovian chain, applicable for GSM/GPRS. A protocol called SIR (service integration for radio access) was introduced earlier [8,9] for mixture of speech-data traffic based on collision free bandwidth sharing. In conventional voice cellular networks, guard channel (GC) is usually allocated for handoff calls to combat forced termination [10].…”

The call admission scheme (CAS) optimizes the use of allocated channels against multi dimensional offered traffic maintaining the required quality of service (QoS). In this paper, a call admission control scheme is proposed for mobile cellular network as an extension of the dynamic partition scheme. The proposed scheme for call admission is based upon the channel borrowing mechanism for voice/data integrated service including thinning scheme of borrowed channel in a one-dimensional Markov model. The model is applicable for underlay overlay mobile cellular network. The proposed scheme has greatly reduced the forced termination (handover failure) of voice calls at the expense of other traffic parameters (blocking of new originated voice call and data call) and the model is also able to make explicit comparison with the different existing call admission schemes like guard channel (GC), dynamic partition (DP) and dual threshold bandwidth reservation (DTBR).

“…The aim of the 3G mobile network is to provide high speed packet communication for real time operation of voice/video-data integrated traffic [1]- [4]. The circuit switched network can carry the traffic at high bit rates at the expense of working with fixed bandwidths.…”
