Abstract


In Wireless Sensor Networks (WSNs), sensor nodes detect environment events and send them to sink nodes, which are responsible for processing these events. Due to the reduced of the nodes, the biggest restriction in a WSN is related to power consumption. Sender-based and receiver-based communication protocols each have their own advantages and disadvantages in certain scenarios. Since a WSN can undergo alterations in time, a protocol that is able to adapt to environmental conditions can increase network lifetime. This paper presents a hybrid routing protocol that operates according to sender-based and receiver-based approaches. The protocol was implemented using the NS-2 simulator and compared to sender-based and receiver-based approaches operating on their own. The results showed that the hybrid protocol, compared to sender and receiver-based approaches, achieves delivery rates close to 100%, performing 2.9 times less transmissions for each packet delivered. These gains demonstrate the contribution of the proposed algorithm, which reduces the number of transmissions, allowing the WSN to have a longer survival time.

Keywords: hybrid sender and receiver protocol, Wireless Sensor Networks, routing protocol, simulations.
