To provide such a capability, it introduces 4 redundancy bits in a 7-bit data item. These redundancy bits are to be interspersed at bit positions 2n (n = 0, 1, 2, 3) with the original data bits. After error detection & correction, if any, the data bits have to be reassembled by removing the redundancy bits. In the proposed improvement the redundancy bits are appended at the end of data bits. This eliminates the overhead of interspersing the redundancy bits at the sender end and their removal at the receiver end after checking for single-bit error and consequent correction, if any. Further the effort needed in identifying the values of the redundancy bits is lower in the proposed novel method. Hamming code is normally used for transmission of 7-bit data item. Scaling it for larger data lengths results in a lot of overhead due to interspersing the redundancy bits and their removal later. In contrast, the proposed method is highly scalable without such overhead. Because of this feature it is suitable for transmission of large size data bit-streams with much lower redundancy bits per data bit ratio","PeriodicalId":403213,"journal":{"name":"2007 2nd International Symposium on Wireless Pervasive Computing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128485752","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}

Due to characteristics such as low data rate, low price, and low power consumption, ZigBee is expected to be used in wireless sensor networks for remote monitoring, home control, and industrial automation. Since one of the most important goals is to reduce the installation and running cost, ZigBee stack is embedded in small and cheap micro-controller units. Since tree routing does not require any routing tables to send the packet to the destination, it can be used in ZigBee end devices that have limited resources. However, tree routing has the problem that the packets follow the tree topology to the destination even if the destination is located nearby. We propose the shortcut tree routing protocol to reduce the routing cost of ZigBee tree routing by using the neighbor table that is originally defined in the ZigBee standard. While following the ZigBee tree routing algorithm, we suggest forwarding the packet to the neighbor node if it can reduce the routing cost to the destination. Simulation results show that the shortcut tree routing algorithm saves more than 30 percent of the hop count compared with ZigBee tree routing.","PeriodicalId":403213,"journal":{"name":"2007 2nd International Symposium on Wireless Pervasive Computing","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121518794","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}

We argue for new mechanisms that can deal with a greater variety of triggering events, which may originate from any component of the node's protocol stack as well as mobility management entities within the network. We present the main concepts that govern our trigger management mechanisms (TMM), which aim at operating in a richer mobility management framework, and enable the deployment of new applications and services. After summarizing the architectural requirements with respect to trigger collection, processing, storage, and dissemination, we introduce a real implementation of TMM on commodity mobile devices. We briefly review our testbed environment and present experimental results using TMM to drive a lossless streaming video session handover between a laptop and a PDA. We position the current TMM design and implementation within the ambient networks architecture, centering in particular on the use of policies to steer TMM operation, and the role that TMM can play in an information service infrastructure.
