“…The works in [4,5] investigate the trade-off between the aggregated packet size and the mandatory delay introduced to assure that enough packets are accumulated in the queue for an optimized aggregation process. If the number of packets to be aggregated is not sufficient but a few packets are buffered in the queue long enough, then only packets with a queueing delay higher than a certain threshold are aggregated.…”

“…The majority of these solutions focus on packet aggregation [1,2,3,4,5,6,7], which works by combining multiple small VoIP packets into a single WiFi frame before transmission, hence lowering the number of frame transmissions required, which further reduces the probability of collision.…”

“…In cite [13] Armenia et al present the implementation of a VoIP testbed on a multihop IEEE 802.11b ad hoc network with stationary hosts and evaluate audio transmission using AODV (Ad hoc On Demand Distance Vector) and OLSR (Optimized Link State Routing) routing protocols. Bayer et al address the problem that small voice packets introduce a high overhead leading to a low voice capacity on 802.11 based mesh networks [14]. In order to alleviate this problem and to increase the voice capacity, they present packet aggregation mechanism.…”

In this paper is considered optimal packet size definition for delay sensitive traffic in WLAN based ad hoc networks. The aim of the paper is to introduce a fuzzy set theory based online sample size definition model, which optimize packet size of delay sensitive traffic for prevailing network conditions. The selected input parameters for the model are a packet error rate (PER) and a change of PER. The model was validated by simulating delay sensitive VoIP traffic. The results prove that the WLAN based ad hoc network with AODV routing and VoIP transactions has an optimal packet size. The results also demonstrate that the developed fuzzy model is able to set sample size values to the prevailing optimum level very fast.

“…While WMN's deployments for PSDR purpose, efficient utilization of the bandwidth is a critical issue especially for audio, text, images or video traffic. Some types of data might be bearing small chunk of packets for control information, though small but numerous packets give rise to considerable amount of overhead for control information in wireless networks [2]. Moreover, such increased overhead is also not affordable in jeopardy situations such as 9/11 and Hurricane Katrina.…”

Wireless mesh networks (WMNs) have found an interesting alternative application in public safety and disaster recovery as they are enabled with key features such as fault tolerance, broadband support, and interoperability. However, their sparsely distributed wireless nodes need to frequently share the control packets among each other for successful data transfer. These packets give rise to a considerable amount of control overhead, especially for multimedia traffic, which is not bearable in jeopardy situations of network disaster such as 9/11 and Hurricane Katrina. Hence, to avoid the huge cost of control overhead, aggregation is supposed to be one of the handy solutions for building a new object from one or more existing objects of network traffic. Generally, aggregation has three types to be executed on 'packets', 'frames' and the 'links' of a network. The network decision B Jin-Ghoo Choi
