A multiroute cross-layer transport protocol with data delivery capabilities for mobile networks is proposed. Protocol combines routing functionality with reliable data delivery. It is shown that finding multiple routes to the destination can be successfully combined with a connection establishment for connection-oriented protocols such as TCP. Establishing a connection over multiple routes can significantly decrease the time of the connection recovery when some routes become unavailable thus increasing total throughput of transport protocol in mobile networks environment. Performance analysis of the proposed protocol indicated that in mobile sensor networks with 5 - 10 % of packet losses its throughput is approximately 60 % higher than throughput of TCP-Reno2 flowing over shortest path.

A method of impulse ultra-wideband signals relaying in ad hoc radio networks is described. As the relaying signals a group of chipsets is used to represent various minimal information units. A system of markers is introduced to unambiguous determine the relaying routes. The chipset representation of transmitted signals reduces the delays coursed by multistep relaying and increases the data transfer rate.
