This ebook constitutes the refereed lawsuits of the seventh Annual Mediterranean advert Hoc Networking Workshop held in Spain on June 25-27, 2008. The IFIP sequence publishes cutting-edge leads to the sciences and applied sciences of data and conversation. The scope of the sequence comprises: foundations of computing device technological know-how; software program conception and perform; schooling; computing device purposes in expertise; communique structures; platforms modeling and optimization; details structures; pcs and society; desktops expertise; safeguard and safety in info processing platforms; synthetic intelligence; and human-computer interplay. complaints and post-proceedings of refereed foreign meetings in desktop technological know-how and interdisciplinary fields are featured. those effects frequently precede magazine ebook and characterize the most up-tp-date study. The critical objective of the IFIP sequence is to inspire schooling and the dissemination and trade of knowledge approximately all facets of computing.

Acknowledgements are aggregated in one packet for every batch. The number of the acknowledgements for both protocols is changed dynamically based on the current link quality. Monitor Module The monitor module is used to monitor current conditions, such as battery level, sensor temperature, link quality and solar power. In our experiments, we use link quality as the main metric to decide if the node's behaviour should be changed. We can use any existing link quality estimation method, such as ETX  or window mean with EWMA .
ExOR is a multihop protocol in which source has global information about routes. In this paper we use ExOR as single link. ExOR is more suited to bad link quality environments than streaming because it uses multiple paths to improve reception. However, when link quality is good, it consumes more energy because of its redundant paths. 2 Energy Consumption Analysis In this section, we compare the performance of the timeout-based protocol, streaming protocol and ExOR protocol in terms of energy consumption.
Additional work must still be done to deeply analyze the influence of the environments on the mobility for PNs, such as collision avoidance, congestion avoidance , etc. Moreover, PNs contains devices involved in different types of networks, such as UMTS, ad hoc networks, sensor networks , etc. The particular behaviors of personal devices in these networks should be considered in the future work of mobility modeling for PNs. For example, swarm behaviors [ 16] of devices in mobile sensor networks should be investigated to address the details of personal nodes mobility in PNs.
