Reliable Data Gathering in Tree-Based IEEE 802.15.4 Wireless Sensor Networks

Abstract

We review the status of hybrid baryons. The only known way to study hybrids rigorously is via excited adiabatic potentials. Hybrids can be modelled by both the bag and flux-tube models. The low-lying hybrid baryon is N 1 2 + with a mass of 1.5 − 1.8 GeV. Hybrid baryons can be produced in the glue-rich processes of diffractive γN and πN production, Ψ decays and pp annihilation.

A Transmission Scheduling for Data-Gathering Wireless Sensor Networks

“…Authors in [8] proposed a routing protocol for enhanced robustness in IEEE 802.15.4-based sensor networks. Similar to our design, they focus on a tree topology network where the sink is the root of tree.…”
