Abstract: In the current world of Technology, wireless sensor communication technology places the major role that led us the innovative idea of using new technology for many applications. This network is applied in many application areas such as in military, agricultural, health care, environmental monitoring, industry, natural disaster prevention, wildlife tracking system, building monitoring, space exploration, security, entertainment, seismic detection, care of the dependent people, and emergency management, dam monitoring, traffic management, and many other areas. There are challenges in providing a reliable data delivery in these applications, such as unique network topology, diverse applications, small message size, resource constraints frequent node failure and congestion. The main objective of this thesis is to improve reliable data transport protocol for wireless sensor network. In order to achieve reliability of data by detecting and recovering lost packet, by making survey on existing reliable data transport protocols, approaches and identified RMST (Reliable Multi-Segment Transport protocol) as best protocol for reliability and lastly make a survey on queue theory. The novel approach, which is named as EERMST (Energy Efferent Reliable Multi-Segment Transport protocol) has developed by hybrid (EACK and NACK), based loss detection, and recovery mechanism to grant reliability. In addition, a novel queue approach has introduced to avoid congestion in multi hop communication. Finally, new approach was tested, and evaluated with different metrics on Tinyos 2.1. x, with Five, Ten Micaz mote, meyer-heavy. txt full noisy file, in 50, 100 ms, and TOSSIM simulator on system application. From the analysis result, the end-to-end delay of EERMST was closer to NACK not more than 0.00046ms but ACK has more delay, which is 0.00231 ms. The delivery ratio of ACK is more and somewhat closer with EERMST but has more packet delay. Generally, the EERMST has less packet delay and more packet delivery ratio than the other protocols.
