Trade-off between Reliability and Energy Consumption in Transport Protocols for Wireless Sensor Networks
Bui Dang Quang, Won-Joo Hwang · 2006
packets are created than the network can carry and the network starts to drop packets. The more packets are dropped, the more energy is consumed and the lesser is the reliability Summary Efficient design and implementation of wireless sensor networks has become a hot area of research in recent years. In comparison with other existing networks, wireless sensor networks (WSN) have some limitations. Typically, nodes in WSN have limited power, computational capacity, and memory. These problems require the need of having particular protocols designed for WSN. Currently, many research focused on developing transport protocols. This paper proposes a probability model that can be applied in transport protocols using hop-by-hop and end-to-end mechanism. From this model, we evaluate the number of hops that a packet has to pass when it is being sent from source to destination. We also solve the optimal number of transmissions in transport layer. The result from this model shows that there is a trade-off between reliability and energy consumption. Key words:
