Abstract
The average symbol error probability (ASEP) and outage probability (OP) performance of mobile-to-mobile (M2M) senor networks employing transmit antenna selection (TAS) and selection combining (SC) over N-Nakagami fading channels are investigated in this paper. Based on the moment generating function (MGF) approach, the exact ASEP expressions are derived for several modulation schemes. The exact closed-form OP expressions are also presented. Then, the ASEP and OP performance under different conditions are evaluated through numerical simulations to confirm the accuracy of the analysis. The simulation results show that the number of antennas, the fading coefficient, and the number of cascaded components have an important influence on the ASEP and OP performance.

Summary
Mobile-to-mobile (M2M) communication is an important proximity communication technology [1]. M2M communication has many advantages, such as increasing data rate, reducing energy cost, reducing transmission delays, and extending coverage area [2, 3]. M2M communication can enable new peer-to-peer and location-based applications and services. M2M communication is widely employed in mobile sensor networks. In contrast to conventional fixed-to-mobile (F2M) cellular radio systems, in M2M sensor networks, both the transmitter senor and the receiver senor are in motion and equipped with low elevation antennas. The classical Rayleigh, Rician, or Nakagami fading channels are not applicable to M2M sensor networks. The double-Rayleigh and double-Nakagami fading models have been considered for M2M channel in [4, 5]. Meijer’s Gfunction was used to analyze the N-Nakagami distribution in [6]
