This ebook constitutes the refereed court cases of the 4th foreign convention on Ad-Hoc Networks and instant, ADHOC-NOW 2005, held in Cancun, Mexico in October 2005.

The 27 revised complete papers offered including the abstracts of two invited talks have been rigorously reviewed and chosen from over a hundred submissions. The papers speak about architectures, protocols, and algorithms for: entry keep watch over, scheduling, advert hoc and sensor networks analytic equipment and modelling for functionality overview, characterization, optimization, auto-configuration, incentives and pricing, position wisdom, discovery, dependence, and administration, mesh networks, new functions, energy administration, strength regulate, and energy-efficiency, quality-of-service, source allocation, multimedia, routing (unicast, multicast, etc.), protection and privateness, provider discovery, structures and testbeds, instant web, and knowledge management.

Otherwise it rejects it. Note, however, that although the possibility of an impersonation attack is reduced, it is not completely eliminated by this scheme. If an adversary jams communications to sensor Sj then it can introduces new commands by “recycling” the unused commitments. One way to defend against this possibility is to assume that sensors are loosely synchronized [15] and commands are issued only at regular time intervals. Then a command issued by an clusterhead at time t will contain commitment kt .

First the clusterhead encrypts the group key using the key Kencr derived from Kij and then creates a MAC σ of the resulting ciphertext c. Then it transmits the message. Observe here that if we make the reasonable assumption that nodes form hierarchies and are organized in a breadth first tree based on some routing protocol, then the group key can be distributed recursively using intermediate level clusterheads until all the sensor nodes at the leaves are reached. Once the group key KiC is settled, the clusterhead can broadcast commands to all the nodes in the group encrypted and authenticated using KiC .
