IJAHUC Special Issue on "Localization, Positioning and Coverage in Wireless Sensor Networks"
by Jaime Lloret Mauri 04 Nov '11

04 Nov '11

Call for Papers Special Issue on "Localization, Positioning and Coverage in Wireless Sensor Networks" International Journal of Ad Hoc and Ubiquitous Computing (IJAHUC) Journal Impact Factor: 0.435 (2010) http://www.inderscience.com/browse/callpaper.php?callID=1741 In Wireless Sensor Network (WSN) deployments, wireless sensor nodes should be strategically placed in order to maximize the sensed area while minimizing the number of nodes to be placed in the field. Moreover, wireless radio coverage distances should be taken into account in order to cover large areas. Wireless sensors may be located quite far from each other, allowing lower deployment costs, but it may increase the wireless sensor node power consumption due to the energy needed to reach large distances. Although many factors may affect the position of each wireless sensor node inside the WSN, there are two main ones: the radio coverage area, which allows the sensors to communicate, and, the sensing coverage area, which gives the sensing region. Both types of coverage areas could be affected by the field where the WSN is deployed, but different factors affect each type of coverage. The goal is to maximize the coverage percentage, while coverage holes should be minimized. This special issue is focused on sensor node location and positioning techniques taking into account the aforementioned constraints. Suitable topics include but are not limited to: - WSN radio coverage. - WSN sensing field. - WSN deployment zones. - Isotropic and sectorial sensing nodes. - Positioning systems. - Node location techniques. - Analytical node placement systems. - 2D and 3D Regions of Interest in WSNs. - Theoretical systems and analytical methods to maximize the radio and sensing coverage. - Sensing gain and power gain systems. - Sleep scheduling techniques for enhancing WSN coverage. - Self-organization Strategies. Submitted papers should not have been previously published nor be currently under consideration for publication elsewhere. (N.B. Conference papers may only be submitted if the paper was not originally copyrighted and if it has been completely re-written). All papers are refereed through a peer review process.

Minutes from RIPE 62, last call on IPv6 Routing Recommendations
by Rob Evans 02 Nov '11

02 Nov '11

All, With very many thanks to the RIPE NCC for their scribing skills, the draft minutes of our meeting in Amsterdam are now available for review: <http://www.ripe.net/ripe/groups/wg/routing/minutes/ripe-62> Please send comments to the list or <routing-wg-chairs(a)ripe.net>. Two matters arising from the meeting: 1 I would now like to start a four week "last call" on the routing recommendations draft so that it can be published as a RIPE document. Please send comments to the list. 2 It is an action on the chairmen of the working group to gather some interested parties in revising the document on Route Flap Dampening. All the best, Rob
