However, BAN wireless communications based on radio-frequency (RF) electromagnetic waves suffer from poor propagation of signals in body tissues, which leads to high levels of attenuation. In addition, in-body transmissions are constrained to be low-power to prevent overheating of tissues and consequent death of cells. To address the limitations of RF propagation in the human body, we propose a paradigm shift by exploring the use of ultrasonic waves as the physical medium to wirelessly interconnect in-body implanted devices. Acoustic waves are the transmission technology of choice for underwater communications, since they are known to propagate better than their RF counterpart in media composed mainly of water. Similarly, we envision that ultrasound (e.g., acoustic waves at non-audible frequencies) will provide support for communications in the human body, which is composed for 65% of water. In this paper, we first assess the feasibility of using ultrasonic communications in intra-body BANs, i.e., in-body networks where the devices are biomedical sensors that communicate with an actuator/gateway device located inside the body. We discuss the fundamentals of ultrasonic propagation in tissues, and explore important tradeoffs, including the choice of a transmission frequency, transmission power, bandwidth, and transducer size. Then, we discuss future research challenges for ultrasonic networking of intra-body devices at the physical, medium access and network layers of the protocol stack.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131910197","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}

With electronic sensors becoming very cheap it will become feasible to deploy large scale sensor networks by simply spreading thousands of disposable sensors on ocean-beds and other earthquake prone areas. However, sensor node populations must be replenished due to their limited battery lifetimes and natural damage. The decision to replenish is driven by the need to maintain a minimum population size for gathering sufficient sensor data for a reliable and timely forecast. It depends on an estimate of the alive sensor node population which is definitely hard to get in this scenario. We obtain a novel design of a first order, time-invariant Wiener filter that robustly estimates sensor node population with very minimal live packet feed from the active sensors. The sensor network is modeled with a G/GI/∞ queue. Our filter can reduce the estimation error by up to 42.7% as compared to an existing approach for a similar estimation problem.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134340996","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}

Mobile devices that operate in the unlicensed band and are not semi-permanently associated with an access point (either residential or business) find it increasingly difficult to compete in the crowded spectrum. An interesting solution is to equip the mobiles with cognitive radios and allow them to identify the set of least occupied channels and hop across them. In our previous work, we have developed the Cognitive Channel Hopping (CCH) protocol, which utilizes a subset of multiple lightly loaded channels, avoiding channels with heavy external interference. While any routing protocol can work with CCH, conventional protocols like DSR and AODV are not well-suited for CCH networks, as they are not designed to work with multiple channels (in the same MANET) and do not take into account other factors that affect the network performance, such as link rates and channel load. In this work, we define a network architecture Cog-Fi, which exploits CCH over multiple channels in MANETs. We devise a routing protocol called CH-LQSR, which further increases the network performance when used in conjunction with CCH. Our evaluation shows that Cog-Fi can exploit channel diversity without explicit coordination. It outperforms conventional approaches in MANET scenarios with multiple flows and heavy external interference.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114263120","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}
