This research will design and develop a protocol that supports less packet drops and consumes a low retransmission time which is able to transmit data in a speedy and efficient manner within a wireless environment. This is vital in real time systems; specifically in way finding applications in order to gather critical information of patients, evade hazardous situations for disable persons, and receive alternative paths in navigation systems in instances of impediments. This research examines the existing Transport Layer Protocols (TLP's); mainly TCP since it has a high rate of data packet loss and high retransmission time when operating in wireless networks. This paper proposes two modified algorithms that solves high packet loss rate by avoiding buffer overflows and high retransmission time by applying a spaced hop methodology. The simulations are performed through the Network Simulator 2 software operating on the Linux platform (Ubuntu) and will graphically and statistically display the improvement achieved by the modifications.
