  1. 6. An Energy-Balancing Unequal Clustering Algorithm for Multi hop Routing in WSN

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sheima Hassan Elamin Hamed; [2013]
    Keywords : Multi-hop routing; Energy balancing; Linear optimization; Network lifetime; Unequal clustering; Wireless Sensor Networks;

    Abstract : Energy saving is a critical issue in Wireless Sensor Networks as they have limited amount of energy and no rechargeable batteries. Clustering plays an effective role in utilization and saving of the limited energy resources of the deployed sensor nodes, where nodes are grouped into clusters and one node, called the cluster head is responsible for collecting data from other nodes, aggregates them and sends them to the BS, where data can be retrieved later.

  3. 7. Cognitive WSN access based on local WLAN traffic estimation

    University essay from KTH/Kommunikationsnät

    Author : Marcello Lagana; [2011]
    Keywords : ;

    Abstract : The recent growth in the deployment of wireless networks that access the unlicensed ISM bands has introduced the issue of co-existence between different kinds of wireless technologies. In this work we address the enhancement of the performance of the low-cost Wireless Sensor Network nodes competing for spectrum access with the WLAN devices, that are more powerful in terms of transmission and computational power.

  4. 8. Design and Implementation of anIPv6 Architecture for Wireless Sensor Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Alexandre Sadones; [2011]
    Keywords : ;

    Abstract : The Diaforus project is a collaborative initiative aiming at building a framework for in-network reasoning in a Wireless Sensor Network. The focus of this thesis is located between the network layer and the application layer, articulated in two distincts parts. READ MORE

  5. 9. On Some Extensions and Performance of Fast-Lipschitz Optimization

    University essay from KTH/Reglerteknik

    Author : Martin Jakobsson; [2011]
    Keywords : ;

    Abstract : A huge range of problems in applied sciences such as engineering and economics can be formulated as mathematical optimization prob- lems. In general, these must be solved by iterative methods whose con- vergence properties to a large extent determines what is achievable. READ MORE

  6. 10. Network Coverage Optimization Strategy in Wireless Sensor Networks Based on Particle Swarm Optimization

    University essay from Akademin för teknik och miljö

    Author : Zihao Fan; Wei Zhao; [2011]
    Keywords : wireless sensor network; particle swarm algorithm; optimization;

    Abstract : Wireless sensor network is an intelligent network system which has the self-monitoring functionality. It consists of many low-cost, low-power and small-sized sensor nodes that can communicate with each other to perform sensing and data processing. READ MORE
