| Abstract | The information plays a key role in the development and well-beings of this society. There is a need to have detailed information about the present conditions of a location, be it an industrial or private building, or even a natural place. There is also a need to have direct values of the human body, like temperature, blood pressure or pulse beat. Gaining access to this information is a new goal for the telecommunication world. This thesis work proposes two forwarding techniques which are suitable for the scenario of the e-SENSE project. The purpose of e-SENSE is to collect information through a wireless sensor network for many applications from sensing the human body to monitoring an industrial environment. The forwarding techniques proposed are optimized to be used in a Publish/Subscribe interaction, in which every node of the sensor network can either be a publisher for a certain information or a subscriber, which acts as a consumer of information. The first technique works in absence of any geographical or deterministic information, without even knowing the address of the destination of the packet. Using the cross-layer information, which is available in every node, the task of the technique is to reach the maximum number of nodes minimizing the energy cost. The second technique works in a scenario in which there is deterministic information in every node about the destination of the packet. The information is not geographical, it simply represents the distance in hop count to the destination. This technique optimizes the number of transmissions using a very simple protocol with low computational complexity. The performances of the two techniques are evaluated through mathematical analysis and are compared to some of the most common forwarding techniques |
