EN The paper proposes a new development environment for implementing and testing multi-criteria routing protocols in wireless mesh networks considered under the CARrier-grade delay-aware resource management for wireless multi-hop/Mesh NETworks (CARMNET) project. The paper presents the justification for choosing Optimized Link-State Routing (OLSR) protocol as the reference CARMNET routing protocol for further extension from a single-criterion to the multi-criteria protocol. The existing software router architectures (Quagga, eXtensible Open Router Platform – XORP, and BIRD) are evaluated. A software and hardware architecture of a single wireless node as well as a network testbed are described. The particular phases of the proposed implementation of the modified multi-criteria OLSR protocol in the nodes of testbed environment are presented. Two types of nodes that differ in processor architecture and energy efficiency are proposed for the testbed. The high performance nodes will be used during the development of the routing protocol, while the low performance nodes (energy efficient nodes) will be used during testing the effectiveness of the protocol elaborated. The developed architecture of the testbed network provides the ability to separate the resources exploited by control functions (routing) and data plane functions (forwarding).
