Our approach employs an adaptive rate based feedback control algorithm using reinforcement learning neural networks (NNs). The reinforcement learning NN controller provides an adaptive optimal control solution. This is achieved via the formulation of a performance measure function (cost function) that is used to, adaptively, tune the weights of the NN. The cost function is defined in terms of two main objectives: (1) to minimize the cell loss rate (CLR), i.e., control congestion and (2) to preserve the quality of the voice/video traffic via maintaining the original coding rate of the multimedia sources. The results show that the NN control system is adaptive in the sense that it is applicable to any type of multimedia traffic. Also, the control signal is optimal in the sense that it maximizes the performance of the system which is defined in terms of its performance measure function. Hence, our novel approach is very effective in controlling the congestion of multimedia traffic in ATM networks.","PeriodicalId":241383,"journal":{"name":"Proceedings IEEE International Conference on Communications ICC '95","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115536116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sectorization, restricted to the simple use of directive antennas at the base station level, is of considerable interest in improving the performance as it can be concluded from the numerical results we obtain.

In the model developed, the channel assignment process is distributed and is governed by the interference environment (C/I). In addition, power control is used in a distributed manner to improve the C/I of an active (call in progress), or inactive channel ( for call admission). System performance is addressed through blocking probability, throughput and call quality. The effect of interference on the efficiency of the above system as compared to FCA is explored under various load imbalances. The sensitivity of the system to load imbalance is also assessed. It is concluded that DCA offers improved throughput performance, responds well to load variations and mobility, and is suitable for distributed implementation.","PeriodicalId":241383,"journal":{"name":"Proceedings IEEE International Conference on Communications ICC '95","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114198874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cash","doi":"10.1109/ICC.1995.525233","DOIUrl":"https://doi.org/10.1109/ICC.1995.525233","url":null,"abstract":"This paper describes a multipoint video bridging architecture, called Montage, that is capable of composing and displaying an arbitrary number of full motion (30 frames/sec) compressed video streams. The system supports end-user-customization, where each end-point controls and customizes the video composition for his/her screen independently of any other participants. The coding and decoding schemes are extremely low delay, on the order of 1 msec coding and decoding, making it possible to support highly interactive applications. The Montage architecture consists of three components connected by a suitable broadband infrastructure, the encoder, the decoder and the video bridge. The Montage decoder has been implemented as a context switchable decoder. This is accomplished by performing all compositing and clipping manipulations on the incoming streams before decompressing them. Much of the functional flexibility of the decoder stems from the the Montage encoder which is unique in that it is capable of compressing full-size (640/spl times/480), entertainment quality NTSC video at 30 frames/sec and simultaneously producing three other reduced resolution compressed streams. As with the decoder, the encoder uses a single commercially available compression chip-set. The video bridge piece of the Montage architecture can take several forms, depending on the capabilities of the broadband fabric and the intelligence of the endpoints. Montage makes it possible to provide continuous presence video teleconferencing in a wide range of scenarios, including local area networks, PBXs, and wide area networks such as ATM.","PeriodicalId":241383,"journal":{"name":"Proceedings IEEE International Conference on Communications ICC '95","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114353090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

WAM banyan switch is constructed using 2d/spl times/2d switch elements. It consists of K parallel banyan switch planes and a packet is allowed to switch/overflow from one switch plane to another when packet contention occurs. This degree of freedom is provided by connecting the d logically equivalent output links from a switch element to d logically equivalent switch elements in the next stage, one in each plane. To further enhance the performance of this switch design, packet broadcasting is used together with priority switching. It is found that under full loading, a WAM banyan switch with K=R=d=3 can have a packet loss probability P/sub loss//spl les/10/sup -6/ for a switch with size up to 4096/spl times/4096.

If users have fixed hopping patterns, a system can monitor the average interference in every time-frequency slot. It can then assign a new user to communicate only in the M lowest interference slots out of every N slots in the user's hopping pattern. The transmit power for the new user is then reduced on the average. System capacity is increased since each user generates less interference. The capacity for a FH-CDMA system in which every user transmits M out of every N slots with equal received power for every user is derived. Power control algorithms which allow users to have different signal-to-interference ratio (SIR) requirements have been implemented to maximize the capacity of the system. In addition, error correcting codes not only protect against interference, noise, and fading, but can also increase the capacity by permitting admission of users even when some of the slots have poor SIR.","PeriodicalId":241383,"journal":{"name":"Proceedings IEEE International Conference on Communications ICC '95","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117184154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
