We choose the Flow-Oriented Routing protocol (FORP), Min-Max Battery Cost Routing (MMBCR) and the traffic interference based Load Balancing Routing (LBR) protocol as representatives of the stability-based routing, power-aware routing and load-balancing routing protocols respectively. FORP incurs the least number of route transitions; while LBR incurs the smallest hop count and lowest end-to-end delay per data packet. Energy consumed per data packet is the least for LBR, closely followed by MMBCR. FORP incurs the maximum energy consumed per data packet, both in the absence and presence of power control. Nevertheless, in the presence of power control, the end-to-end delay per data packet and energy consumed per data packet incurred by FORP are significantly reduced compared to the scenario without power control. MMBCR is the most fair in terms of node usage and incurs the largest time for first node failure. FORP tends to repeatedly use nodes lying on the stable path and hence is the most unfair of the three routing protocols. FORP also incurs the smallest value for the time of first node failure.","PeriodicalId":292238,"journal":{"name":"2009 Sixth International Conference on Wireless On-Demand Network Systems and Services","volume":"76 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128777920","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}

Researchers focus on improving their power efficiency in order to allow building up networks that survive for long periods of time on limited battery resources without any human intervention. Improvements have been proposed for every hardware and software component, including every networking layer of the sensor nodes. Concerning the MAC layer, different strategies have been proposed, among which preamble sampling is promising. This technique limits the energy spent by nodes that are not recipients of a frame, and transfer a part of this cost to the transmitter. However, the basic technique leaves room for enhancements. We show that such optimization is possible by adapting the duty cycles of the nodes taking into consideration their depth in the routing tree. We experimentally demonstrate that a significant reduction in energy consumption may be obtained when using different preamble lengths throughout the network. Our results show that, with such inter-layer cooperation, the energy efficiency of nodes closer to the sink can be improved by up to 50%.","PeriodicalId":292238,"journal":{"name":"2009 Sixth International Conference on Wireless On-Demand Network Systems and Services","volume":"7 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120995803","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}

A Single Random Walker (SRW) is another popular mechanism for information dissemination that is very “slow” compared to flooding but utilizes less overhead and can potentially achieve better coverage than flooding. The latter may be attributed to the better “stretching” properties (ability to visit further away network regions) of the SRW and is particularly observed if coverage is defined as the set of network nodes which are at most L hops away from a network node which received the information (notion of L-coverage, L ≥ 0). Randomly Replicated Random Walkers (RRRWs) are considered in this paper as a broad class of information dissemination mechanisms whose members are defined by a given value of the (first) replication probability; clearly a SWR corresponds to the RRRWs with zero (first) replication probability, while for values of the (first) replication probability close to one a large number of information disseminating agents (RWs) are generated resembling the operation of flooding. By considering various performance metrics (such as the achieved coverage for a given message-forwarding budget and the time required to spend the available message-forwarding budget), and by considering various network topologies (such as Random Geometric, Erdös- Rényi and Clustered environments), we show that the class of RRRWs can “fill” the performance space, between the performance induced by flooding and the SRW, thus offering a richer set of information dissemination strategies that can better match desirable performance constraints or objectives.","PeriodicalId":292238,"journal":{"name":"2009 Sixth International Conference on Wireless On-Demand Network Systems and Services","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134276921","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}
