  • Rate Allocation with Lifetime Maximization and Fairness for Data Aggregation in Sensor Networks

    Publication Year: 2008 , Page(s): 1 - 6
    Request Permissions | Click to expandAbstract | PDF file iconPDF (263 KB) |  | HTML iconHTML  

    We consider the rate allocation problem for data aggregation in wireless sensor networks with two objectives: 1) maximizing the lifetime of a local aggregation cluster and 2) achieving fairness among all data sources. The two objectives are generally correlated with each other and usually they cannot be maximized simultaneously. We adopt a lexicographic method to solve this multi-objective program...

    Energy efficiency and low message delay are the basic QoS requirements for data collection in vehicular ad-hoc and sensor networks. In order to achieve these requirements, many solutions have been developed by attaching collectors/sinks to vehicle or aircraft and moving them either randomly or along a predefined route. This paper presents an adaptive data gathering protocol (ADG) that employs mult... View full abstract»

    Power consumption is a critical issue in many wireless sensor network scenarios where network life expectancy is measured in months or years. Communication protocols typically rely on duty-cycle mechanisms to reduce the power usage at the cost of decreased network responsiveness and increased communication latency. A low-power radio-triggered device can be used to continuously monitor the channel ... View full abstract»

    The directional sensor placement problem is an essential part of any planning model for directional wireless sensor networks. Its goal is to find an optimal subset of locations where directional sensors should be placed so that the total network cost is minimized while the requirements of coverage and connectivity are satisfied. Directional sensors are characterized by three important parameters: ... View full abstract»

    In this paper, we consider sensor database systems. Sensors are attached to objects and queries on the objects are operated at the sensor network level. Although queries to such a system might be extremely complex, ensuring efficiently basic functionalities such as broadcast or anycast without any central element is not trivial. In this paper, we provide a suite of *-cast (anycast, k-cast, broadca... View full abstract»

    The coupling of mobile ad-hoc networks (MANETs) and the Internet is gaining attention by researchers working towards future ubiquitous computing environments. In this work, we focus on the situation that occurs when specialized, sensitive data are sent to the Internet from MANET nodes. These special data types are especially susceptible to security risks such as information leak and data falsifica... View full abstract»

    In the past few years there has been increasing research interest in service discovery protocols for mobile ad hoc networks (MANET). The most promising approaches so far address energy efficiency by merging the service discovery process with the routing process. Actually the service information is piggy-backed into routing messages, so that a node is simultaneously informed of available services a... View full abstract»

  • Accurately Predicting Residual Energy Levels in MANETs

    To support energy-efficient routing, accurate state information about energy level should be available. But due to bandwidth constraints, communication costs, high loss rate and the dynamic topology of MANETs, collecting and maintaining up-to-date state information is a non-trivial task. In this work, we use Optimized Link State Routing (OLSR) as the underlying routing protocol and focus on residu... View full abstract»

    This paper proposes a dynamic energy efficient clustering algorithm for mobile ad hoc networks (MANETs). The proposed algorithm elects first the nodes that have a higher energy and less mobility as cluster-heads, then periodically monitors the cluster-heads' energy and locally alters the network topology or the clusters to increase the network lifetime by reducing the energy consumption of the suf...
