However, since operating all nodes in power-save mode limits network capacity, some nodes may need to stay in active mode to support forwarding. The main challenge of selecting nodes to stay in active mode stems from the need to conserve energy while maintaining communication. Although topology management protocols build a forwarding backbone of active nodes by powering down redundant nodes, such protocols incur proactive backbone maintenance overhead. The reactive approach, on-demand power management, manages node transitions from active to power-save mode based on routing information. However, node transitions are only traffic-driven and may result in keeping redundant nodes awake. To this end, we propose TITAN, which builds a backbone reactively using information about both ongoing communication and the current power-management mode of nodes. The design of TITAN is based on the trade-offs between waking up power-saving nodes on shorter routes and using longer routes that contain active nodes. Simulation results show that TITAN conserves energy while maintaining efficient communication without additional control overhead for topology management","PeriodicalId":268267,"journal":{"name":"IEEE International Conference on Mobile Adhoc and Sensor Systems Conference, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129888770","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}

Yet, there is no agreement on how to analyze the lifetime of a WSN. As a result, errors are frequently made on both sides. Some underestimate the network lifetime by an order of magnitude, while others end up overestimating the lifetime by a significant factor. This paper presents a first step towards standardizing the lifetime analysis of WSNs. We focus on WSNs deployed for always-on applications, where the problem of power management is most severe because the environment needs to be monitored continuously. Underestimation of network lifetime is common when proposing sleep-wakeup schemes, where it is frequently assumed that in the absence of a sleep-wakeup scheme, a sensor node from the Mica family lasts 3-5 days on a pair of AA batteries. We show that the same sensor node can be made to last more than 36 days, even if it is continuously monitoring the environment. Overestimation typically occurs when proposing non-sleep-wake up power management schemes such as in-network data aggregation. Overestimation occurs because several network activities (e.g periodic routing messages) are assumed to have negligible effect on the network lifetime and therefore are ignored in the lifetime analysis. We use our recent experience in deploying ExScal (a large-scale WSN for intrusion detection) to identify major components in the network lifetime analysis. We then present a careful lifetime analysis of ExScal and show how to analyze the effects of using various non-sleep-wake up power management schemes such as hierarchical sensing, low-power listening, and in-network data aggregation on the network lifetime. Our lifetime analysis will be useful as a template in analyzing the lifetime of other WSNs deployed for always-on applications","PeriodicalId":268267,"journal":{"name":"IEEE International Conference on Mobile Adhoc and Sensor Systems Conference, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121792076","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 the protocol, each event detected by sensors is associated with an intensity value (delta)(by sensors), where delta is a parameter that depends on the characteristics of the event and the application context. When event information is broadcast, a sensor decides whether to store the record of an event by checking its distance to the event location and the delta. In general, the higher the intensity of an event, the further its information can propagate geographically in the sensor network. Besides, the closer to the event location, the denser the sensors are that store the event information, and thus the quicker and better a user can know about the event (by reading from surrounding sensors). The protocol utilizes network resource efficiently. In particular, the storage load of sensors is independent of the network size, and is evenly distributed across the network. Moreover, the communication distance for getting event information is small. Therefore, the protocol has great scalability. We provide detailed theoretical analysis and simulation study to support the claims. We also ran simulations to show the advantage of our protocol over some previous work. LCS can be used for applications such as context-dependent information mining in pervasive computing and on-demand warning in surveillance sensor networks","PeriodicalId":268267,"journal":{"name":"IEEE International Conference on Mobile Adhoc and Sensor Systems Conference, 2005.","volume":"746 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115837206","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}
