TinySPOTComm: Facilitating Communication Over IEEE 802.15.4 Between Sun SPOTs and TinyOS-Based Mote

The increasing popularity of sensor network has spawned a wide range of platforms and frameworks for sensor network development. While in theory nodes based on different frameworks should provide radio stack compatibility, in practice this is rarely the case. The authors explore this problem by providing a case study and introduce TinySPOTComm, a customized radio stack for the Sun SPOT platform which allows for radio communication between IEEE 802.15.4 based TinyOS motes and Sun SPOTs. The TinySPOTComm radio stack remains fully compatible with the Sun SPOT radio stack and its network performance is only marginally affected in comparison to the default Sun SPOT radio stack.
