Design and analysis of an efficient communication strategy for hierarchical and highly changing ad-hoc mobile networks
by Ioannis Chatzigiannakis, Sotiris Nikoletseas — 2004 — In ACM/Baltzer Mobile Networks Journal (MONET), Special Issue on Parallel Processing Issues in Mobile Computing, Guest Editors: A. Zomaya
…In this work we introduce two practical and interesting models of ad-hoc mobile networks: a) hierarchical ad-hoc networks, comprised of dense subnetworks of mobile users interconnected by a very fast yet limited backbone infrastructure, b) highly changing ad-hoc networks, where the deployment area c…

Adaptive Energy Management for Incremental Deployment of Heterogeneous Wireless Sensors ∗
by Ioannis Chatzigiannakis, Athanassios Kinalis, Sotiris Nikoletseas — 2005
…We introduce a new modelling assumption in wireless sensor networks, that of node redeployment (addition of sensor devices during the protocol evolution) and we extend the modelling assumption of heterogeneity (having sensor devices of various types). These two features further increase the highly d…

Adaptive Techniques for Proactive Collision Avoidance for Multi-path Data Propagation in Wireless Sensor Networks ∗
by Ioannis Chatzigiannakis, Athanasios Kinalis, Sotiris Nikoletseas
…Data propagation in wireless sensor networks can be performed either by hop-by-hop single transmissions or by multi-path broadcast of data. Although several energy-aware MAC layer protocols exist that operate very well in the case of single point-to-point transmissions, none is especially designed a…

A Mobility Sensitive approach for Efficient Routing in Ad Hoc Mobile Networks
by Athanasios Bamis, Ioannis Chatzigiannakis, Azzedine Boukerche — In the proc. of the 9th ACM/IEEE International Symposium on Modeling, Analysis and Simulation of Wireless and Mobile systems (MSWiM
…In ad-hoc mobile networks (MANET), the mobility of the nodes is a complicating factor that significantly affects the effectiveness and performance of the routing protocols. Our work builds upon the recent results on the effect of node mobility on the performance of available routing strategies (i.e.…

Routing Protocols for Efficient Communication in Wireless Ad-hoc Networks
by Ioannis Chatzigiannakis, Ioannis Chatzigiannakis, Panagiotis Kokkinos, Panagiotis Kokkinos, Christos Zaroliagis, Christos Zaroliagis — 2006 — In 3rd ACM Workshop on Performance Evaluation of Wireless Ad Hoc, Sensor, and Ubiquitous Networks (PE-WASUN
…In this paper we demonstrate the significant impact of the user mobility rates on the performance on two different approaches for designing routing protocols for ad-hoc mobile networks: (a) the route creation and maintenance approach and (b) the “support ” approach, that forces few hosts to move act…

Distributed communication algorithms for ad hoc mobile networks
by Ioannis Chatzigiannakis, Sotiris Nikoletseas, Paul Spirakis — 2003 — Journal of Parallel and Distributed Computing (JPDC
…An ad-hoc mobile network is a collection of mobile hosts, with wireless communication capabilities, forming a temporary network without the aid of any established fixed infrastructure. In such networks, topological connectivity is subject to frequent, unpredictable change. Our work focuses on networ…

Efficient and Robust Data Dissemination using Limited Extra Network Knowledge
by Ioannis Chatzigiannakis, Athanasios Kinalis, Sotiris Nikoletseas — 2006 — in the Proceedings of the IEEE International Conference on Distributed Computing in Sensor Networks (DCOSS), Lecture Notes in Computer Science (LNCS
…Abstract. We propose a new data dissemination protocol for wireless sensor networks, that basically pulls some additional knowledge about the network in order to subsequently improve data forwarding towards the sink. This extra information is still local, limited and obtained in a distributed manner…
