2. 1. Experimental Challenges in Wireless Sensor Networks — Environment, Mobility, and Interference

   Author : Olof Rensfelt; Per Gunningberg; Torsten Braun; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Testbed; Mobility; Interference classification; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Abstract : Wireless sensor networks are used to collect sensor data in different applications such as environmental monitoring, smart building control, and health care applications. Wireless sensor nodes used are typically small, low-cost, and battery powered. READ MORE

4. 2. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

   Author : Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

   Abstract : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. READ MORE

5. 3. Opportunistic Networking : Congestion, Transfer Ordering and Resilience

   Author : Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Mario Gerla; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic Networking; Congestion; Transfer Ordering; Resilience; Testbed; WISENET; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Abstract : Opportunistic networks are constructed by devices carried by people and vehicles. The devices use short range radio to communicate. Since the network is mobile and often sparse in terms of node contacts, nodes store messages in their buffers, carrying them, and forwarding them upon node encounters. READ MORE

6. 4. Supporting Internet Access and Quality of Service in Distributed Wireless Ad Hoc Networks

   Author : Ali Hamidian; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoS Guarantees; EDCA; IEEE 802.11e; IEEE 802.11; Mobile Ad Hoc Networks; Wireless Mesh Networks; Internet Access; testbed;

   Abstract : In this era of wireless hysteria, with continuous technological advances in wireless communication and new wireless technologies becoming standardized at a fast rate, we can expect an increased interest for wireless networks, such as ad hoc and mesh networks. These networks operate in a distributed manner, independent of any centralized device. READ MORE

7. 5. On a robotic Matlab Java testbed for mobile robots

   Author : Sven Rönnbäck; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Abstract : This thesis presents the MICA (Mobile Internet Connected Assistant) testbed and how it can be used to interface a mobile robotic system; in this case a modern wheelchair equipped with a CAN bus. In MICA we do research in embedded Internet systems, sensor technologies, navigation algorithms and in the knowledge about user. READ MORE
