No single positioning technology can meet the localization requirements across the range of location-aware or location based services. However, for many value added services, it is possible to use locations approximations within certain tolerable thresholds. This paper, in particular, examines how GSM infrastructure can be leveraged for localization of low cost mobile phones with adequate approximations to meet the requirements of certain location aware services especially in countries like India. The feasibility of the approach is demonstrated by pathfinder service (prototype of a location-aware road navigation utility) for Indian cities where road network is very ill structured compared to those in American or European cities. It provides text based driving instructions to a destination when a mobile phone user sends a query via SMS. We also looked at the theoretical issues arising out of optimal shortest path computation over semi-structured road networks and propose a new algorithm for the same.","PeriodicalId":369006,"journal":{"name":"2010 Second International Conference on COMmunication Systems and NETworks (COMSNETS 2010)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127818793","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 wireless sensor networks, the nodes resemble individuals in a way that they communicate with their peers, sometimes selectively hiding some information, sometimes selectively exposing some other information, generating or forwarding information, sharing resources, joining and/or leaving the network. We argue in this paper that nodes of the sensor network have their own social life, and based on that assumption, we leverage ideas from social networks to show how the nodes can communicate in a “social networking” style to achieve significant efficiency. Specifically, we study the performance of WSN when some common rules of social network are applied in WSN and show significant reduction of overhead traffic leading to longer battery life of embedded nodes and better utilization of the network. Results from theoretical analysis have been verified through experimental study to justify the benefits of treating WSN as a social network.","PeriodicalId":369006,"journal":{"name":"2010 Second International Conference on COMmunication Systems and NETworks (COMSNETS 2010)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124323560","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}

The technique is based on preprocessing of signal at the transmitter relying on knowledge of the channel state information. This a priori information is available in time division duplex (TDD) mode due to channel reciprocity. In practice, errors in channel estimation occur due to time varying nature of mobile radio channels and also due to method adopted for channel estimation. Most of the previous works on Pre-Rake for TDD/DS-CDMA systems have not taken into consideration the effect of errors in channel estimation. In this paper, we analyze Pre-Rake performance under imperfect channel estimation with generalized orthogonal (GO) codes. We also present a pilot-based correlation method for channel estimation and evaluate the Pre-Rake system through analytical and computer simulations for TDD/DS-CDMA downlink.","PeriodicalId":369006,"journal":{"name":"2010 Second International Conference on COMmunication Systems and NETworks (COMSNETS 2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129008522","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}

Since energy availability can be different across nodes in the network, network setup and collaboration is a non trivial task. At the same time, in the event of excess energy, exciting node collaboration possibilities exist; often not feasible with battery driven sensor networks. Operations such as sensing, computation, storage and communication are required to achieve the common goal for any sensor network. In this paper, we design and implement a smart application that uses a Decision Engine, and morphs itself into an energy matched application. The results are based on measurements using IRIS motes running on solar energy. We have done away with batteries; instead used low leakage super capacitors to store harvested energy. The Decision Engine utilizes two pieces of data to provide its recommendations. Firstly, a history based energy prediction model assists the engine with information about in-coming energy. The second input is the energy cost database for operations. The energy driven Decision Engine calculates the energy budgets and recommends the best possible set of operations. Under excess energy condition, the Decision Engine, promiscuously sniffs the neighborhood looking for all possible data from neighbors. This data includes neighbor's energy level and sensor data. Equipped with this data, nodes establish detailed data correlation and thus enhance collaboration such as filling up data gaps on behalf of nodes hibernating under low energy conditions. The results are encouraging. Node and network life time of the sensor nodes running the smart application is found to be significantly higher compared to the base application.","PeriodicalId":369006,"journal":{"name":"2010 Second International Conference on COMmunication Systems and NETworks (COMSNETS 2010)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128004411","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}
