This work investigates the deployment of active networking on mobile devices. The objective is to determine the possibility of decreasing energy consumption on mobile devices accessing Internet services, by use of active networking. The approach is to move the TCP/IP stack from the mobile device onto an access point. To enable this a light-weight protocol based on Bluetooth has been implemented to...
This paper is investigating the energy saving potential of Bluetooth. Using the asynchronous connectionless link (ACL) for data transmission, Bluetooth provides different packet types, namely DM and DH packets. Each packet has a different payload size and in the actual implementation the packet selection is based on the channel conditions. In this paper we present and discuss results of a measurements...
Over the last years mobile phones had a remarkable evolution. From a simple device for voice communication, it became a full blown multimedia device with multiple features and appealing services. In parallel with the introduction of novel services, mobile devices became more and more energy-hungry reducing the operational time for the user. To extend the battery life of mobile phones is one of the...
Localization information retrieval is breaking new ground for mobile applications for indoor or urban areas. GPS is the positioning technology that powers the majority of the navigation devices today, it comes along with high complexity, high energy consumption and limited coverage for indoor. The main idea of this paper is to exploit cooperation among mobile devices to retrieve their geographical...
In this paper, bio-inspired cooperation rules are applied to wireless communication networks. The main goal is to derive cooperative behavior rules to improve the energy consumption of each mobile device. The paper describes a medium access control (MAC) protocol particularly designed for peer-to-peer communication among cooperative wireless mobile devices. The work is based on a novel communication...
In this paper, we give an overview of the emerging directions in wireless location according to the Cooperative Mobile Positioning (COMET) project. The latter proposes innovative solutions for the fourth generation (4G) mobile localization, which directly originate from investigating the impact of cooperation among heterogeneous terminals in hybrid cellular ad-hoc networks. Besides launching a promising...
This paper focuses on the header compression for wireless technologies with fixed link layer packet types. Exploiting specifics of packet transmission over air in this situation, a novel IP header compression scheme is developed. The novelty of the scheme consists in the unique CONTEXT repair mechanisms that ensured high robustness and at the same time does not degrade bandwidth savings. After the...
This paper advocates a novel approach for mobile web browsing based on cooperation among wireless devices within close proximity operating in a cellular environment. In the actual state of the art, mobile phones can access the web using different cellular technologies. However, the supported data rates are not sufficient to cope with the ever increasing traffic requirements resulting from advanced...
