In this paper, the problem of mobility handling in wireless sensor network (WSN) is studied with a simple priority backoff technique. To incorporate this technique for stationary and mobile sensor nodes, a novel hybrid MAC protocol called VMAC is designed with a fixed frame length. VMAC combines the advantages of schedule-based MAC for energy savings and(More)
This paper presents the development of high power AlGaN/GaN HEMTs on GaN/SiC epi-materials in MACOM Technology Solutions. Instead using state-of-the art via-hole technology popular in the GaN HEMT industry to have the common-Source on the device bottom, our Source-contact is designed on the device top-surface for enhancing its surface thermal dissipation as(More)
