Therefore, it is desirable to find a routing path such that all edges in the path are long-lived. Based on the ad hoc on-demand distance vector routing (AODV) protocol, we propose an AODV-RSS (AODV with received signal strength) routing protocol such that connectivities of links in the route found can sustain longer. The AODV-RSS algorithm uses the received signal strength, RSS9 and the received signal strength changing rate, ARSS, to predict the link available time, LAT. Using the LAT as a constraint, our method will find out a satisfying routing path. Simulation results show that our routing algorithm can greatly improve the quality of the routing path in route connection time, and route reestablishment frequency.","PeriodicalId":145728,"journal":{"name":"2006 1st International Symposium on Wireless Pervasive Computing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129254304","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}

In a mobile Ad-hoc Network (MANET), support for multicast communication is essential in order to minimize overhead for group communication. For group conferencing services, controlling the end-to-end delay is important to provide high quality communication. In this paper, we present QAMNet, an approach to improve the Quality of Service (QoS) for multicast communication in MANETs. We extend existing approaches of mesh based multicasting by introducing traffic prioritization, distributed resource probing and admission control mechanisms, adaptive rate control of non-real-time traffic based on Medium Access Control (MAC) layer feedback so as to maintain low delay and required throughput for real-time multicast flows. Simulation results show that our approach is as scalable as mesh based deliver structures and does not require significantly more states than normal mesh based multicasting protocols. As we reuse signaling packets of mesh based multicast packets, we do not introduce additional signaling overhead.","PeriodicalId":145728,"journal":{"name":"2006 1st International Symposium on Wireless Pervasive Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130943355","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}

Several energy-aware packet scheduling schemes are explored and discussed. Using the average delay of non real-time packets and the rejection rate of real-time packets as performance metrics, a scheduling scheme for this purpose is proposed. It is composed of two scheduling stages. In the early stage, each packet type is scheduled independently on the per type basis. They are then merged using PGPS into the second stage where the transmission speed for each packet is assigned. The packets are then transmitted using dynamic modulation scaling (DMS). The method has been evaluated using simulation and compared against one in which energy savings schemes are not incorporated. The result shows that not only does it provide a fair share of bandwidth (low rejected packets for real-time packets and low delay for non real-time packets) between these streams, but it also saves the overall transmission energy, particularly in the light load case, where as much as 90% savings can be obtained.","PeriodicalId":145728,"journal":{"name":"2006 1st International Symposium on Wireless Pervasive Computing","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133724983","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}

An Address Proxy Agent (APA) is proposed to be implemented in the radio network controllers (RNC) to provide a residual address for the mobile host (MH) with RSVP reservation during the handover process. The principle of this approach is to provide a residual address for MH that is valid in radio network sub-system (RNS) and traceable back to MH latest location. W hen MH send a packet upstream the APA will replace the packet source address with the residual address before releasing the packet to the rest of its RSVP path. And when RNC receives a return RSVP packet destined to this residual address the APA will replace this residual address back to the source address and forward this packet to the current location. This approach confines the impacts of a handover to the local RNS yet maintain PSVP path as MH moves from one cell to another.","PeriodicalId":145728,"journal":{"name":"2006 1st International Symposium on Wireless Pervasive Computing","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121037268","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}
